  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
  }
