I've just taken a look at Mikmatch, and it looks pretty straightforward to
add an ocaml-re (pure OCaml) version of the extension, and very useful at
that.  It's not on the critical path, so likely sometime in May, but on my
todo list now.

Right now, it has a Str and Pcre backend, both of which are supported by
ocaml-re (as well as globbing and other styles).  We can't really depend
on ocaml-pcre due to all the C dependencies of course.
