We (the nmag/nsim dev team - http://nmag.soton.ac.uk) kind-of had the
opposite problem, i.e. we had to extend a scripting language that is 
easy to learn with something that has a bit more steam. We decided to
use Python+OCaml. There's a semi-abandoned debian package, pycaml,
that does this, but that's broken - it has memory management bugs
both oh the Python and OCaml side. Here is a fixed version that also
supports a few nice extensions:

I should say that being able to extend Python with fast code without
having to worry about allocating/destroying things and having the
convenience of simple callbacks both ways is a very nice thing.
