Suggestion 1: DEFAULT VARIABLE. Always, always, always use $_ to avoid having to explicitly feed args.

Suggestion 2: Regexen: abuse the hell out of 'alternate begin/end chars' (m;foo;).

Suggestion 3: Quote operators. Abuse the 'alternate' quote operators, such as qq, q, and qx, along with their alternate end/begin chars.

Suggestion 4: Use map, not variables and fors, and pipe yer list from one map to another.

Suggestion 5: (Ab)use whitespace and 'end of lines' (aka semicolons) and put them in semi random spots. So instead of my $faz='foo';print $foo, do something like

my $faz
=
'foo'
;print$foo;

Suggestion 6: Comments are also fun, but make them misleading. i.e. $_=$; #assign my dollar sign to $_, as this can help mess people up.

Suggestion 6: builtin variables. Learn to love them always. $;='fooz' is much more fun then $s1='fooz'.


Over all, you can go two ways. First (the bestest) is to be misleading. Evals + alternate quoting operators are fun to abuse here. Secondly (boring) is to just jumble as many maps and special vars + random punctuation together as you can, while the first is probably the best, the second can be almost impossible to figure out (without lots of effort), and is probably easier.
