There are some funcs that may tide you over in the meantime, or at least give you a starting point to write replacements for regexes you need.

* whitec (test for a whitespace char)

* nonwhite (inverse of above)

* alphadig (test for alphanumeric chars)

* punc (true for any of [.,;:!?])

With the functions all and some, and a little subseq-fu you should be able to do what you want.

edit: Also look around the forum here for a patch to subseq to support negative indices for slicing off the end.
