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
ad40123b25 Master's error recovery and return types read off the body live together, and two ways out of an inferred body that cannot share a type are refused with both named 2026-09-25 19:58:31 +07:00
ff88b9dad6 A defn whose return slot is _ (or a .fln fn with no arrow) takes its return type from its own body, recursion through such functions is refused by name, and a stale caller of one is told which line changed its type 2026-09-25 17:09:13 +07:00
4c336687ef Master's error recovery is merged, and the refusal memos are consulted only where a refusal is raised 2026-09-25 17:03:32 +07:00
4b64dc5f65 Code-carrying dev requests name their syntax and starting line and column, so a .fln snippet sent from the middle of a buffer reads with the buffer's own locations 2026-09-25 15:57:09 +07:00
25e303caf4 Master's indented reader is merged, and its x += v over a place with a call in it reads as update, evaluating the place once 2026-09-25 15:56:51 +07:00
074b2da6f3 The indented reader refuses a continuation line that is not deeper than its statement, takes one-line statements in arms, then/else and defer, typed lets and bare-name blocks, and names the shape it wanted where it used to say two values cannot sit side by side 2026-09-25 15:30:52 +07:00
8cc63ed9f6 A place in update, ++ and -- evaluates each of its subexpressions once, and (update place f args ...) stores (f old args ...) back into it 2026-09-25 15:26:27 +07:00
d7016f91c7 A .fln file is read by an indented reader that yields the paren reader's forms, every program entry point picks the reader by extension, and flan convert prints either syntax as the other 2026-09-25 15:04:32 +07:00
22d2a4cfb2 An indented surface beside s-expressions is specified as a second reader chosen by file extension 2026-09-25 14:21:51 +07:00
