The reader expanded ^X form to (with-meta form X), which evaluated the tag (so
^String errored 'Unable to resolve symbol: String') and, as a param, was no
longer a bare symbol (so the arg bound to nil). Now a keyword/symbol/string hint
on a symbol attaches to the symbol's :meta and the symbol stays bare, so type
hints are transparent in params, lets, and bodies. Map metadata still uses a
runtime with-meta form.
meta now returns a symbol's :meta, and def applies the name's metadata
(^:dynamic, ^:private, ^Type tag, ^{:doc}) to the var, so (meta (var x)) is
consistent. Specs in metadata-spec; grammar note in the ebnf.
README notes regex \p{...} as unsupported (separate from this).
- grammar.ebnf: rewrite the number rule to cover the literal syntaxes the reader
now accepts — 0x/0X hex, N (bigint) / M (bigdec) suffixes, ratios a/b, radixed
integers (NrXXX, base 2..36), exponents, and the ##Inf/##-Inf/##NaN symbolic
floats — noting Jolt reads them as plain Janet numbers.
- README: Numbers bullet notes the literal syntaxes read; conformance count.
- reader-syntax-spec: drop the stale 'ratio not supported' case; add coverage
for hex-uppercase/N/M/ratio/radix/exponent/##Inf/##NaN.
- PLAN.md: refresh the stale Current State snapshot for the 3-layer test
structure (spec/integration/unit), ~3,920 suite assertions, 218/218
conformance, current source size.
jpm test green.
