Ok now that I feel like I have gotten over the grep hurdle, I've run into map and tried to apply it to part of the code I'm currently working on. Now, I've looked through any of the postings regarding map, though some of them are beyond my needs, so I've decided to experiment for a bit and ran into this snag: 
  my @sub_locs2;
  for (@session_keys) {
   if ($_ =~ /taxman.add.subloc./) {
     $_ =~ s/taxman.add.subloc.//g;
     push @sub_locs2, $_;
   }
  }


  my @sub_locs = map { $_ =~ s/taxman.add.subloc.//g if $_ =~ /taxman.
+add.subloc./ } @session_keys;

@session_keys contains the following:
taxman.add.subloc.20
taxman.add.level
taxman.add.value
taxman.add.loc
taxman.add.sel
taxman.add.subloc.1
taxman.add.code
taxman.add.subloc.16
taxman.add.subloc.19
taxman.add.name
taxman.add.lvid

The for loop above does exactly what I want it to do, step through each element, modify it if it matches a pattern and push it into a new array. That's what map is supposed to do right? What it's doing now, is that map is affecting each element that matches the pattern and modifying the respective element in @session_keys, is this another precedence issue? Ok... what am I missing?
