As an exercise I've made a library in Python that holds feature
structures (with some nice interfaces and recursive structure, so you
could do avm[SYNSEM][LOCAL] or avm[SYNSEM.LOCAL], etc.), and it did
some unification, but was by no means fast.
This isn't the library what you're looking for, but I thought I'd
throw it out there in case anyone is interested.
