I'm going off-topic, but I've wished we had a generic fast string-search
(and replace?) procedure.

The go-build-system has a slow "one byte a time" implementation because
I couldn't figure out how to re-use the code in (guix build grafts):

https://git.savannah.gnu.org/cgit/guix.git/tree/guix/build/go-build-system.scm?h=v1.2.0#n269

There are probably some other places we could use a fast procedure. It
might even be something to add to Guile.
