- Function calls are f(a, b) via a postfix argument list; juxtaposition
application removed; nullary calls f() supported
- Wire DEFINITION (x ≜ e), ALLOC/RELEASE postfix (r ⊕ / r ⊖), channel
operations (⇀_ch e / ↽_ch e), and qualified module access (M‧f)
- Delete tokens with no rule and no example: QUERY (?), EXISTS, IMPORT,
ARROW, DOT; delete the unary ? prefix operator
- Canonical handler clause: ↯pattern ⟹ expr (pattern is an identifier or
a string); clauses separated by semicolons
- SEMICOLON has one role: sequence separator with optional trailing use
- Disambiguate braces structurally: record ({a: e}), set ({a, b}), block
- IDENTIFIER no longer allows a leading underscore, so subscripts such as
⌉_db_lock and ↽_socket lex as UNDERSCORE + IDENTIFIER
- Add '/' as ASCII alias of ÷; add unary minus; pathLiteral accepts
🖫identifier as well as 🖫"…"
- Exactly one ASCII escape per glyph (drop \lam, \gets, \ne, \le, \ge,
\vee, \wedge, \cup alias forms, \N, \Z, \Q, \R, \C, \B)
- Replace deprecated ANTLRInputStream with CharStreams in the test
harness: it fed UTF-16 units and could never tokenize the
supplementary-plane glyphs 𝔹, 𝓜 and 🖫
- Update LexerTest/ParserTest to canonical syntax; add coverage for
subscript lexing, channels, resources, module access, unary minus,
nullary calls, and negative tests for juxtaposition and the ternary
