OK. Thanks.

Lisp - the only thing I've seen is a translator:

http://dan.corlan.net/R_to_common_lisp_translator/

I haven't found a binding for Haskell. Nor for Scheme.

Do you know of any bindings of R to functional languages?

You expressed the sentiment that it would be a very bad idea to bypass 
the current API. I would be happy to hear why you would think that a 
low-level binding is not possible, or not very viable.

By low-level, I mean a binding that takes hold of R objects without 
using symbols all over to reference them. (Using symbols in the formals, 
the body or the environment of a closure is fine, for instance, but I'd 
like to execute a closure directly, and eventually be able to construct 
R closure from OCaml functions).

Please elaborate on the difficulties you perceive. That would be helpful.

All the best,
