Revision history for Infix-Custom

0.01    2026-06-20
        First version.
        - Lexically-scoped custom binary infix operators, built on core's
          PL_infix_plugin hook (perl 5.38+), installed via wrap_infix_plugin.
        - Declarative import API:
            use Infix::Custom op => '<glyph>', call => \&sub, prec => '<tier>';
          plus the shorthand  ('<glyph>' => \&sub, ...).
        - Lowering modes: call mode (LHS op RHS -> sub(LHS, RHS)), op mode
          (binop => '+' lowers to a native binary op, no call overhead), method
          mode (method => 1: RHS read as a bareword method name via a parse
          stage, so safe-navigation `$o ?-> meth` works under strict), and a
          C-level build_op escape hatch (pass a function-pointer IV) for XS
          authors who want to emit a custom optree.
        - import()/unimport() are implemented in XS: argument parsing, the
          precedence vocabulary, glyph validation, registration and the lexical
          %^H hint are all done in C; only the bootstrap stays in Perl.
        - Precedence by friendly name mapping to core's INFIX_PREC_* ladder;
          associativity follows the chosen tier.
        - Lexical scope and nested rebinding via %^H; an out-of-scope glyph is
          an ordinary parse error. Longest-match resolution between glyphs.
        - Requires perl 5.38+ (the PL_infix_plugin hook); does not install below.
