Module keywords 

The single source of truth for the language’s keywords.

Every keyword’s CAPS spelling lives exactly once, in kw. The KEYWORDS table attaches each one’s role (may it begin a statement?) and its syntax card (canonical form, one-line gloss, a copy-paste example). Everything else in the workspace that needs to know a keyword — the reserved-word check, recovery resync, the diagnostic cards, the parser’s tag(...) calls, and the compiler’s provenance kind strings — derives from this table or references a kw constant, so a keyword string is never written twice.

Modules

kw

The CAPS spelling of every keyword — the one place each literal appears.

Structs

Card

The correct-syntax reference for one keyword: its canonical written form (with <slots> and [optional] parts), a one-line plain meaning, and a real, valid example a model can copy. Mirrors docs/SPEC.md, “DSL: keywords”.

Keyword

One keyword: its spelling, whether it may begin a top-level statement, and its syntax card.

Constants

KEYWORDS

Every keyword, in teaching order. The top-level statements come first (so filtering top_level yields the menu order), then IMPORT/AS, then the body and modifier words.

Functions

card_for

The syntax card for keyword, or None if it is not a known keyword.

is_reserved

Whether word is a reserved keyword.

is_top_level

Whether word can begin a top-level statement (used by recovery resync).

keyword_in

The first keyword named anywhere in message (selects its card in a diagnostic). Splits on non-alphabetic characters and returns the first token that is a keyword.

top_level_forms

The keywords that may begin a top-level statement, in teaching order — shown as the menu when an error is not tied to one specific keyword.
