I did not know about Boost::Python. On reading it, it seems that, though horrible, it would be easy to port to any Common Lisp out there. If I were to write that, though, I would not do it as they do, with such undecipherable template code -- templates perhaps yes, but at least attempting something more readable.

I have given it a try https://github.com/juanjosegarciaripoll/cl-cxx

It is indeed not that hard to define wrappers for C++ functions using templates as they seem to properly dispatch among functions with different arities. Implicit or explicit conversions are also easy to implement, given the proper Common Lisp back-end.

Best,
