I was trying to make a list of all the strings that would match something like [0-9a-zA-Z]{3}, to get from 000 to ZZZ, and all separated by a newline. At first I was making nested loops, but then thought that, if I wanted something of length 7, I didn't want to type another loop with another variable, etc. However I hate recursion, even though I'm sure that would have been the smallest, and probabbly most efficient result. I ended up with this little beauty, which doesn't deobfuscate much with perltidy or -MO=Deparse.

I also know I've used every punctuation variable I could, and broken all the rules, haha. It's not as compressed/golfed as it can be, it's just...a mess.
Code: 
#!/usr/bin/perl
sub generate_list{$_=q!$;=@_[0];$;--;$_='(0...9,"a"..."z","A"..."Z")';
+for($i=0;$i<=$;;$i++){$*.="\@t$i=$_;";$@.="for(\$c$i=0;\$c$i<=\$#t$i;
+\$c$i++){";}$.=$*.$@;$:='print';for($,=0;$,<=$;;$,++){$:.="\$t$,\[\$c
+$,\].";}$:.='$/;'.'}'x($;+1);return$..$:;!;eval eval}generate_list 2;

Hope you like it :)
(I know it's one of the least efficient ways of doing this, haha)
