Some more information. AFAICT there are really only three places that need
to be looked at:

  1. class_rep.cpp:319

     It should be enough to do the string building in some other way,
     probably using lua_concat().

     It's possible that the std::map<>::find() call needs to be moved
     out to another function as well.

 2. make_function.hpp:67,76

    This should be fine. But I can't tell for sure since there's black
    magic involved.
