in thread OO systems and Perl 5 (Was: Recap: Future of Perl 5)

A suitable implementation of UNIVERSAL::new could provide similar default behavior to Perl 6's new. So could a suitable implementation of UNIVERSAL::init - and would be more friendly to "immigrants" from other languages' OO systems - Class::init will be called with an already blessed object, so will only need to perform initializations (and, maybe, validate supplied parameters). (Not surprisingly, overriding new in Perl 6 requires the new class's new method to use bless to create the new object.)

    Unfortunately ammending UNIVERSAL will certainly break some CPAN modules.

    Just imagine packages trying to catch new in AUTOLOAD.
