Changes for version v0.011 - 2026-01-26

  • NEW: Added closure interface with make_filter() function for maximum performance
  • make_filter() creates optimized, reusable closures that can be 20-25% faster than hand-written Perl filtering code due to pre-computed exclusion lookups and specialized closure variants
  • Three specialized closure variants:
    • Required-only (empty accepted list) - 3.1M ops/sec
    • Wildcard (accepted contains '*') - 1.3M ops/sec, 24% faster than raw Perl
    • Accepted-specific (normal case) - 1.8M ops/sec, 20% faster than raw Perl
  • OPTIMIZED: filter() function now uses same optimizations as closure interface:
    • Pre-computed exclusion hash (O(1) lookups instead of O(n) array search)
    • Hash slice for required field copying (faster bulk operations)
    • Non-destructive operations with hash lookups instead of delete
    • Single wildcard check instead of per-iteration checks
  • All interfaces (functional, OO, closure) now use identical optimization techniques
  • Closure interface is 142-239% faster than functional interface due to:
    • No input parsing overhead (hashref-only input)
    • No error message construction overhead
    • Pre-compiled closures optimized for specific configuration
  • Added comprehensive test suite for make_filter() (t/04-make_filter.t with 10 subtests)
  • Added complete POD documentation for closure interface
  • Added usage examples (examples/closure_interface.pl with 6 working examples)
  • Added benchmark scripts:
    • benchmark-three-variants.pl - Performance comparison of three closure types
    • benchmark-optimized-filter.pl - Optimized filter() vs make_filter() comparison
    • benchmark-make_filter.pl - Closure vs raw Perl performance
  • Updated README.md with closure interface documentation and performance notes
  • Updated performance considerations to clarify that closure interface provides maximum speed while functional/OO have feature overhead
  • Changed "database queries" to "database statements" for accuracy (includes inserts/updates)
  • All 73 tests passing across 6 test files
  • POD syntax validated
  • Full backward compatibility maintained
