I often need to use the [ | ] # characters in text, like this
kick $1 $$2 $3 [ Victim # $+ %kicks ]
Of course this won't work right, since they're reserved characters. So you need to use $chr(), and it's annoying to have to look up the ascii code. I think there should be the additional identifiers $[, $|, $], and $# which just return the corresponding character.
