Three small unblockers in one iteration:
- tokenizer: read-digits! now consumes optional ".digits" suffix,
so 3.7 and ¯2.5 are single number tokens.
- tokenizer: ⎕ followed by ← emits a single :name "⎕←" token
(instead of splitting on the assign glyph). Parser registers
⎕← in apl-quad-fn-names; apl-monadic-fn maps to apl-quad-print.
- eval-ast: :str AST nodes evaluate to char arrays. Single-char
strings become rank-0 scalars; multi-char become rank-1 vectors
of single-char strings.
