Revision history for Destructure-Declare

0.02    2026-06-20
        - Fix load failure on perl < 5.21.6 ("undefined symbol: op_convert_list",
          reported by CPAN Testers on 5.14.4) 

0.01    2026-06-19
        First version.
        - compile-time `let` keyword (lexical pragma), lowered to a plain optree
        - array patterns [ ... ] over an arrayref; hash patterns { ... } over a hashref
        - nested patterns, holes (undef), per-slot // defaults (lazy)
        - list patterns ( ... ) destructure a list (list-context RHS)
        - trailing slurpy: @rest / %rest on array & list patterns, %rest
          (remaining keys) on hash patterns (custom ops)
        - right-hand side evaluated exactly once
        - fast path: a flat array/list pattern (plain scalars, holes, optional
          trailing slurpy; no defaults or nesting) lowers to a single native
          list-assignment, matching hand-written `my (...) = ...` speed; the
          `( )` list form skips the arrayref copy entirely. xt/bench.pl covers it.
        - publishes its compile-time engine (include/destructure.h) via
          ExtUtils::Depends, so dependent dists (e.g. Switch::Declare) can
          #include it rather than carrying a copy
