Subject: ?z character class vs. "valid character" class
What is the ?z (any character) class used for? Is it used anywhere, by
anyone? It's current meaning is indeed *any* character, valid or not.
Reason I ask is that we are contemplating a "valid" class, that can be
used to reject candidates containing characters not valid for the chosen
codepage. The ?v name came to mind but it's already taken. Now I noticed
the ?z and I can't really think of any use for it - but if we modify it
to mean "match any *valid* character" I see many uses.
Maybe it was meant for PP stuff, much like the ':'. Failing to hijack
?z, any other suggestion for a better letter?
