Just a guess, but would declaring it as:
void mySlightlyHelpfulFunction(const cppmodule::A &a)
work better? (Note insertion of "const")
The {lvalue} in the signature output suggests that the problem could be that
Boost.Python is internally constructing a C++ temporary cppmodule::A value
and trying to pass it into mySlightlyHelpfulFunction().
