Stuff with the Perl Foundation. A couple of patches in the Perl core. A few CPAN modules. That about sums it up.

Missing Features

[ #34986 ]

For my Array::AsHash module, there's an obvious feature that I just didn't think about: allowing subrefs.

$hash->values( sub { ucfirst } };

You might even want that for the keys since the can be references:

my @parents = $hash->keys( sub { $_->parent } );

Well, duh!

  • I really like that. It would be very useful way of filtering.

    It would be slick to use in an each too. Very ruby-ish.

    while ( my ($key, $value) = $array->each( sub { /^foo/ } ) {
        # iterate over array like a hash
    }

    Or something similar to your example:

    while ( my ($key, $value) = $array->each( sub { ucfirst } ) {
        # iterate over array like a hash
    }
