Why not just a character class? It's usually a bad idea to use alternation
in these cases. m!^[/%#\s\$]+$! should do the trick. Or if there must be
three #'s in a row, perhaps m!^ (?: [/%\s\$]+ | \#{3} )+ $!x ?
In any case, you should consider if this is the right approach - There are
hundreds of characters you probably don't want ( (?{ `echo "Hope you didn't
use re 'eval';"` }) ), so the chance of going back and changing your program
is high; It's an uphill, never-ending battle.
Meanwhile, there only a handful of character that you actually want -
Mayhaps /^\p{L}+$/ will do the trick?
