The London Perl and Raku Workshop takes place on 26th Oct 2024. If your company depends on Perl, please consider sponsoring and/or attending.

Changes for version 1.18

    • Type constraint objects now have an assert_coerce method which will either return a valid value or throw an error. (rjbs)
    • We now warn when an accessor for one attribute overwrites an accessor for another attribute. RT #57510. (Dave Rolsky)
    • The native Array and Hash delegation methods now coerce individual new members if the _member type_ has a coercion. In other words, if the array reference is defined as an ArrayRef[DateTime], and you've defined a coercion from Int to DateTime, then pushing an integer via a delegation method will coerce the integer to a DateTime object. Reported by Karen Etheridge. RT #62351. (Dave Rolsky)
    • An attribute using native delegations did not always properly coerce and type check a lazily set default value. (doy and Dave Rolsky)
    • Using a regexp to define delegations for a class which was not yet loaded did not actually work, but did not explicitly fail. However, it caused an error when the class was loaded later. Reported by Max Kanat-Alexander. RT #60596. (Dave Rolsky)
    • Attempting to delegate to a class or role which is not yet loaded will now throw an explicit error. (Dave Rolsky)
    • Attempting to set lazy_build in an inherited attribute was ignored. RT #62057. (perigrin)
    • The Moose test suite now uses Test::Fatal instead of Test::Exception. (rjbs)
