[Openmcl-devel] string handling question

No, not homework :-)
(subseq "asd" 1 2) eventually calls (%substr "asdf" 1 2) once it
satisfies all it's criteria.
I'm looking for a similar optimization for FIND and friends when the
argument is a string.
(FIND #\s "mystring")
eventually boils down to
(dovector (a "mystring")
(when (eq a #\s) (return a)))
but some implementations of strchr are smarter then that and would do
things in 4 or
8 byte chunks.
Since I'm working on an OpenMCL editor, implementation dependence is
not a problem.
