What I want is to use c preprocessor to generate easy wrappers around c++
class methods. For every class, I would like to make a
lisp class, which would have one slot containing the actual void* point,
and macros would generate functions which will autocast
cl_object and/or the slot value of the item into c++ type. However, what I
would like is to install new methods for these c functions.
