Your indices function sounds sorta like the smart match code that I heard theDamian talk about at his Perl6 talk -- well, at least knowing whether "heimer" is in the list.

Of course, you could write your own indices() function pretty quickly, using a sort of modification of the Schwartzian Transform (I actually have tested this, on a few cases, but let me know if I've missed anything): 

sub indices ($@) {
  # note the prototype has target, then list
  my $target = shift;
  my (@list) = @_;

  my $index = 0;
  map { $_->[1] }
    grep { $_->[0] eq $target }
      map { [$_ , $index++] } @list;
}

I'm sure some wizard out there could tighten this up, but I think it's pretty clear what I'm aiming at.
