Try map:
%hashtable = map { $ctr++, $_ } @files;
Or even:
%hashtable = map { $ctr++, $_ } <*>;
Of course, I've probably got the syntax wrong - since I
don't use map that often. You can, of course, write many
programs in terms of sub/map like:
sub add {
return map {
#do processing
} @_;
}
which can really annoy your coworkers.
