Well, I did know of parse. (: But I was thinking of something that
applies a standard function to every value in a series. I'm sure I'd
seen some word that does that.
And parsing's so different from standard REBOL that switching over to
it is difficult for those who haven't used it enough for it to have
stuck in their mind. I have to re-learn it whenever I have to do
more than the most basic splitting. And it doesn't help that strings
and blocks are treated differently...

** Script Error: Invalid argument: char
No doubt it's for performance reasons, but anyway...
