in thread Moose and default values

Nice, but why does it live in "PerlX" and not in "Moose" or "MooseX"?

    Probably you can use it outside Moose, too.

      Indeed; it has no ties to Moose. It's simply a function that takes a list and returns a (possibly smaller) list. While it's handy to use it with Moose/Mouse/Moo constructors, it can be used with any functions that take a list of key-value pairs that you want to filter out undefs from.

      package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name
        It's nice (and only 10 lines of code :-=).

        But say I now wanted not only undefs but everything that is false (e.g. also an empty string) to trigger the default?

        Does Moose not have any mechanics for that?
