e6ea657263 The array literal given a slice type by the matches a read-only slice too 2026-09-25 13:41:49 +07:00
b2eb81f7bf A slice or pointer can be read-only, and what it reaches cannot be written through it 2026-09-25 13:39:04 +07:00
f3d969618d A class slot can carry a type, and set writes a declared slot 2026-09-25 13:32:16 +07:00
c6ad71dc5b A value that owns storage is never copied out of read-only storage, and two arguments at one type variable meet at const 2026-09-25 13:30:47 +07:00
8eca8c78f2 The checker refuses what it cannot type honestly and says which element is wrong 2026-09-25 13:29:56 +07:00
5066b8d288 The literal an array cannot hold is the element blamed, a negative literal in a generic body names a fix for every instantiation, and a doubly negated literal is positive 2026-09-25 13:29:42 +07:00
53880eb685 A class slot's type names its own package's class first, an int widens into a float slot exactly when it round-trips, and a constructor's refusal names the call that was wrong 2026-09-25 13:29:30 +07:00

4742d7e7ef A closure that outlives its call keeps its captures on the collector's heap 2026-09-25 13:09:40 +07:00
1e5be63a1a An array reached through read-only storage slices to a [const T], a Vec or Map copied out of one stays read-only through lets, and an if's const and writable branches meet at const in either order 2026-09-25 13:08:29 +07:00
9394a26449 A negative literal fits no unsigned type, u64 included, and the refusal names the cast that writes its bit pattern, which a constant now folds 2026-09-25 13:02:50 +07:00
325c3662a8 A numeric type's limits are (max-value T) and (min-value T), and an array literal of numbers with no common type is refused with the conversion named 2026-09-25 12:56:02 +07:00

9ba99d7d5b A dev build puts every closure handed to a named call on the collector's heap, since a redefinition can make the callee keep it 2026-09-25 12:55:56 +07:00
16427f8d07 A class slot may be a class or an Option, an int widens into a float slot when exact, a gained typed slot starts at its zero, and a migration never re-enters itself 2026-09-25 12:55:25 +07:00

35f455acb3 The's refusal of a dyn says what the boundary does at that type, elements that cannot become a dyn are refused against each other, two literal arms meet at the wider type, and the renamed prelude function and a second startup warning stay out of sight 2026-09-25 12:49:02 +07:00
37e577d5e1 (Ptr const T) is documented beside [const T], and the TODO entries for it are closed 2026-09-25 12:46:07 +07:00

d8945ae4ae The address of read-only storage is a (Ptr const T), which nothing is written through and which a C const T * parameter takes 2026-09-25 12:43:04 +07:00
d3ac1ab4dc Type limits are spelled min-value and max-value, and quick formatting is to use a per-frame temporary allocator 2026-09-25 12:20:12 +07:00

c6cb018b9f Only a closure that outlives its frame takes a collector environment, and the collector reads a Vec's elements only through a block it knows is live 2026-09-25 12:12:25 +07:00
c0b4b22357 Growing, shrinking or freeing a container reached through a [const T] is refused, and a function that only reads a slice stands where one that may write it is wanted 2026-09-25 12:10:47 +07:00
bf0a939093 A dyn negation of a non-number is refused by name, and a prelude function shadowed in a live session is a recorded gap 2026-09-25 12:07:32 +07:00

5e9be2150f A generic's name disassembles to each of its copies, and completion knows the name 2026-09-25 12:01:06 +07:00
77497cfc2c A generic's copy made by an evaluated expression is disassembled from that expression's module, and one copy that cannot be shown no longer hides the others 2026-09-25 12:00:50 +07:00
5c0698d749 (max-of T) and (min-of T) are a numeric type's limits, at a concrete type or a type variable the bound admits, and given a slice they are still the prelude's reductions 2026-09-25 12:00:42 +07:00
9bb1bde665 A defn with no return type says so, and an operator spelled as another language spells it names Flan's 2026-09-25 11:57:09 +07:00
f629123561 A lowercase vec, ptr, option or map over types in a return slot is a near miss for its constructor, and a bare && is written back as the (and) that compiles 2026-09-25 11:56:56 +07:00

2ea47f91eb A program's function named as a prelude function takes the name over for its own file, with a warning, and the prelude's own calls keep the prelude's 2026-09-25 11:51:58 +07:00

d6217830ff A defn whose body stands in its return slot is told it has no return type, a misspelled type constructor is a near miss, and not=, ==, &&, || and their kin name the Flan builtin that computes the same thing 2026-09-25 11:50:23 +07:00
7cf57eb8ba A read-only slice refuses a dyn view without promising one later, and taking a read-only element's address is recorded as an open decision 2026-09-25 11:49:17 +07:00
c671bba490 (the T e) gives any expression its type, and an array literal nothing names is typed when its elements agree and a dyn vector when they mix 2026-09-25 11:47:28 +07:00
