Does emacs-lisp have any character classification predicates?  I'm thinking like maybe 'letterp' or 'digitp' or 'alphanump' (names I made up, of course).



I could do this with regexps ("[[:alpha:]]", etc), but that seems like kind of a big hammer to use for individual characters.  I was thinking that maybe something could be done with the case-table, but I haven't figured that out yet.



Thanks in advance!

Why do you need them?  What problem are you trying to solve?
