I suspect that if there was a real need for this and an XS solution does actually provide substantial speed gains over substr or the reverse and chop trick then it'd have already been done.

Most times a smarter algorithm gives much more bang for the buck than tinkering with an implementation to make the old algorithm a little faster.
