I explained poorly. I don't want to bind lua or python to Ocaml. I
want to bind C++ to ocaml.

Can you expand on C++'s staticness, and why OCaml is not dynamic enough for it?

Luabind can't bind entire templates -- it can only bind instances of
templates. I'm perfectly happy accepting this lmitation, i.e. having
to have separte:

std::vector<int>
std::vector<Foo>
std::vector<Dog>

Binding a piece of code from C++ to anotehr langauge involves 3 steps
(1) template magic to get the type of the member/function
(2) some sort of reference counting
(3) generating the code for the binding

(1) & (2) is already provided by pythonbind/luabind/slb
The question is (3) ... which I think can be automated once.
