For over 25 args for a member functions of an exposed class I get the following compiler error: /usr/include/boost/python/detail/invoke.hpp:81: error: must use ‘.*’ or ‘->*’ to call pointer-to-member function in ‘f (...)’
I believe this is because BOOST_PYTHON_MAX_ARITY doesn't have the ability to change the hardcoded limit of 25 parameters in boost/type_traits/detail/is_mem_fun_ptr_impl.hpp, which boost.python uses. This is why I recommended that workaround.
