My very own little JAPH

Be nice this is my first one, (boss is gone today! :) )

$s1='!,@,#,$,%,;,&,+,.,:,>,7,?,<';$s2='@,#,B,D,E,0,F,C,A,6,4,<,5,9'; sub mrg{return @_;}@a=split /,/,$s1;@c=split /,/,$s2;foreach(@a){$n= ord($_);@d=mrg(@d,chr($n+ord($c[$i])));$i++;}print@d[4,13,11,12],' ' ,@d[0,7,8,12,3,2,10],' ',@d[9,2,10,6],' ',@d[3,0,1,5,2,10],"\n";

Suggestions are very welcome!

After reading the BUU's suggestions I made some modifications: here's try #2 :)

$;= '!,@,#,$,%,;,&,+,.,:,>,7,?,<,9,5,<,4,6,A,' .'C,F,0,E,D,B,#,@';$|= 1;sub mg{return@_}eval{ @_=split /,/,$;;@ARGV=reverse(splice(@_,14,27) );$;=();map{@{$;}=mg(@{$;}, chr(ord($_) + ord( $ARGV[$i])));$i=$i+scalar(@_)-13;}@_;@ARGV=mg( @_,@ARGV);print@{$;}[4],@{$;}[13],@{$;}[11],@{ $;}[12],' ',@{$;}[0],@{$;}[7],@{$;}[8],@{$;} [ 12],@{$;}[3],@{$;}[2],@{$;}[10],' ',@{$;}[9,2, 10,6],' ',@{$;}[3,0,1,5,2,10],"\n";}##########

    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.

    ++ on the second try, now i can officially say, "i have no bloody clue what its doing", which is always the point of a true obfuscation.

    One final thought on seeing the second try, is that you might want to try playing around with obscuring functions, i.e. instead of doing "print $foo", you could do something like "@_=q:print:;push @_,$foo; eval pop;pop;". While thats not an incredibly good example, im sure you could do better.
