Dear monks,

I have YAEP - yet another efficiency problem (but you could also think of it as "Yet another elegance problem"): I'm doing a glob expansion of a list. let's say you have a list @params and this contains some filename globs. You'd like to expand this list to be explicit. i.e. 

(*.txt *.aux) -> (file1.txt file2.txt file1.aux file2.aux)

So ok. What I'm doing right now is: 
sub globlist {
  my @back;

  foreach my $elem (@_) {
    push @back, (glob $elem);
  }

  return @back;
}

[download]
and then just @param = &globlist(@param); Waaah. Bad solution. I know it - I feel it. Much copying way too much overhead, too much code. I'd like to walk through the list and modify it without copying the expanded data to a new one. But when I try splice to do that, I get lost with the index.

Does anyone of you know the right path to listglobing?

Bye
