Class-Abstract-0.03

Changes for version 0.03 - 2026-11-05

  • Incompatible Changes
    • $config{harness_bypass} now defaults to 0: enforcement is no longer switched off when HARNESS_ACTIVE is set, so test suites catch accidental instantiation of abstract classes. Set it back to 1, or use local $Class::Abstract::BYPASS = 1, to restore the old behaviour.
  • Bug Fixes
    • Bump minimum Test::Mockingbird, fixes RT#178677
    • is_abstract(), new() and check_abstract() no longer create the package they are asked about in the symbol table
    • Class::Abstract->is_abstract($obj) now checks the object's class (it used to check the stringified reference and always return 0)
    • is_abstract() croaks on an unblessed reference, as new() does
    • Objects blessed into package '0' are accepted as invocants
    • undef elements in @ISA no longer cause warnings
  • Enhancements
    • check_abstract()'s unblessed-reference message names the reftype
    • POD rewritten: per-routine examples, API specifications, messages and Z specifications; LIMITATIONS section
  • Tests
    • New t/locales.t; regression tests for all of the above
