79430aca77 A lambda's last form is checked at the return its position wants, a call's arguments and a kept cond with no else keep a when as an Option, a when used as an arithmetic operand is blamed itself, elif let reads and prints as a nested if-let, and dyn get over text or a vec runs at's own runtime body. 2026-09-26 13:09:21 +07:00
a3899f3ecb Master is merged into the when, get and if let lane for the review fixes. 2026-09-26 12:53:34 +07:00
28d4c0f8dc A number literal takes its type from its uses inside the function, an unconstrained float literal is an f64, and a dyn use asks for the dyn width. 2026-09-26 12:41:54 +07:00
36655025c0 Master is merged into the when, get and if let lane again. 2026-09-26 12:23:17 +07:00
62fd7b19bc Master is merged into the when, get and if let lane. 2026-09-26 12:13:55 +07:00
5ee433a38f A kept when answers an Option, get is a checked lookup over arrays, slices, Vecs and dyn, and if let reads as a two-arm match in both syntaxes. 2026-09-26 12:12:48 +07:00

ca9e28860a A dyn value into a written type has a checker row that compiles. 2026-09-26 11:52:13 +07:00
6d8ced2ba3 A dyn text becomes a str as its own bytes, a dyn view becomes its own storage, and a dyn vec or map becomes a checked copy in a [const T], a fixed array or a struct, while a writable [T] is never a copy. 2026-09-26 11:48:01 +07:00
bcdb6250a9 A bit operator's operand of any shape that answers a bool gets the and, or or not hint, found by a check that is thrown away. 2026-09-26 11:46:32 +07:00
c7fb0e5422 Literal locals fed through do, let and if arms share one type without extra rounds, a chain past the rounds names the local to annotate, a restart's conversion fix shows the argument as written, and a name's lookup is answered from the last one under the same scope 2026-09-26 11:14:15 +07:00
5712d4bdc0 A bool operand of a bit operator is refused with its and, or or not hint in a whole-file check, whichever operand it is. 2026-09-26 11:04:32 +07:00
473bf0a2b7 The bit operators are && || ^^ ~~ in .fln at Python's precedence, take integers only on typed and dyn values, and popcount, leading-zeros, trailing-zeros and the rotations exist on both backends. 2026-09-26 10:49:54 +07:00
23663c4773 An unconstrained float literal is an f64, literal locals settle by merging the locals that feed each other, and a restart refused for a number type writes the conversion 2026-09-26 10:45:46 +07:00

5f1b9b9e7e An unconstrained float literal is an f32, and an integer literal meeting a float literal meets it at the float 2026-09-26 09:49:51 +07:00

5177586848 A number or character literal bound by let or loop takes its type from its uses in the function 2026-09-26 06:22:25 +07:00
f39612bc7c Code a request sends without :syntax is read in its file's syntax, or the program's when it names none, and a dotted dyn name points to its accessor. 2026-09-26 06:21:07 +07:00
7953376e4e Any typed container of numbers, bools, str, structs, arrays, slices or Vecs crosses into dyn as a view from any storage, and a dev build traps on a view whose frame returned or whose block was released. 2026-09-26 06:10:11 +07:00
b92e91bcaa A parameter, local or field may be named str or any other type name when a type follows it, and a type-named parameter with no type after it is refused with both fixes. 2026-09-26 05:27:23 +07:00
267db2cd91 The typed read-only text type is spelled str, and string is refused with that fix. 2026-09-26 05:22:24 +07:00
263214e639 A dyn opened by an expectation is marked where it is opened, so a bool or an Option beside a dyn stays a dyn, and an operand refused at a type is not asked again, so nested sums and matches check in linear time 2026-09-25 23:43:14 +07:00
3e504deb6f An arm is checked at the other arm's type first and meets it at the join only when refused there, so every program master accepts keeps its type and value while arms still meet in either order 2026-09-25 23:10:16 +07:00

a39d96149d slice-from-ptr is refused with the slice-from call to write, and the pointer cast's const rule is documented as covering the outer pointer only 2026-09-25 22:35:24 +07:00
70b9040512 type-of answers a dyn value's kind as a keyword, and a class cannot be named after a built-in kind 2026-09-25 22:29:26 +07:00

e80411d283 type-of answers a value's kind as a keyword or an instance's class name, and a class named like a kind is refused. 2026-09-25 22:18:36 +07:00

ff0679cbb1 An if's else arm is checked once and brought to the join, an abandoned check undoes only what it wrote, and an arm refused at the join says why at its value 2026-09-25 22:14:06 +07:00
a1e5e39dba Master's changes are merged into the dyn printing lane, with its converter fixture 2026-09-25 22:11:04 +07:00
4f060bb648 Dyn and typed containers print as [1 2 3] and {:a 1}, a refused dyn view names the value and a dyn fix in the file's own syntax, and a dyn function whose body gives no value says so by name 2026-09-25 22:01:40 +07:00

18581a452c = and != compare bools, a match over a bool takes true and false arms, a match over a dyn takes keyword arms, and where predicates joined with and are refused with the comma or vector form as the fix 2026-09-25 21:35:31 +07:00
ed7258c80f An abandoned check puts back everything it wrote into the environment, an else arm refused on its own terms is not blamed for the then arm's type, and a match's arms meet at the same join as an if's 2026-09-25 21:26:56 +07:00
ab5fe36a48 A frame address stored into a global's field, array or Vec element, or pushed or put into a global container is refused with a fix that names no wrong type, and the sanitizer sweep builds at -O0 so a read of a returned frame reports 2026-09-25 21:18:48 +07:00

f76d0d6e9f An if's arms and a _ function's exits meet at one join in any order, a return inside the last form counts where it is written, and a constant computed by a _ function is refused as with a written type 2026-09-25 21:02:26 +07:00
76b2ab3113 A duplicate literal arm is one whose value equals an earlier arm's at the scrutinee's type, and a literal no dyn holds is refused with a pattern fix 2026-09-25 21:01:15 +07:00

a6ccce0e67 Every store of a frame address into a global outside main is refused, fn and handler bodies and restart clauses are checked as frames of their own, and the suggested clone keeps the slice's bounds 2026-09-25 20:50:17 +07:00

df7078d586 A _ function's exits combine exactly as an if's arms do, a refused _ body or loop is collected with every other error, and the placeholder type never leaves the checker 2026-09-25 20:37:50 +07:00
8fdf8513fd A _ body's errors are reported with every other error in the file, a literal return takes the type of the other exits, and a recursive _ function that gives nothing returns () 2026-09-25 20:17:44 +07:00
