    s///eg and the hash table disguised as an array, plus basic bamboozling with difficult characters. In a more transparent form ...

    %_=(62 => 20, 38 => 1, 35 => 50, 33 => 2, 60 => 10, 37 => 5); # Match each chunk of optional characters in a specific order # Look up the ASCII values of each char in the chunk in the hash # Add the hash values plus a starting value of 30 # Replace the chunk with the character whose ASCII you just added up # (Pattern modified to add \s* so that chunks could be # formatted prettily) s:#*>*<*%*!*&*\n*\s*: $;=30; $;+=$_{+ord} for split'',$&; chr$; :eg for $_=q:>>!! #><%&& >>>>% >><<<<%& ! #<%! #>< >>><<& #<<<!&&&& #<<!&& >>>%%& >><<%%%%&&&& ! >>< #>& >>><<!! >>>%%%&&& ! ><<<<<&&&& >><<%! >><%%%&&&& #>%&& >>><& >>>>&&&&:; print;

    Remember, when you stare long into the abyss, you could have been home eating ice cream.

[Discipulus]: a solution would be disabiltate sig as default and let users to show them
