What we really need is a validating parser/loader/scanner, one for each
scheme. I've been skimming through the schemes and noticed there's some
repetition in Rebol's open functions, which could be abstracted out. Also,
if a validating parser rule was incorporated into each scheme to check for
wellformedness, that would be good. As it stands now, I can't use Rebol's
'load/next function to extract a URL from plain text with punctuation around
it. For example extracting the URL from the following: "Rebol's HQ"
http://www.rebol.com! requires me to write my own URL parser.
