[REBOL] Re: brainfart parse problem
From: timewarp:sirius at: 6-Jun-2001 14:12
this is kind of what i want, but the "valid"s
aren't individual characters, they are a series
of characters, so doing a charset is out. how
would i get the same effect given that the "z"
and "y" were actually "zyx" and "yza"?
