It seems to be. Here's the error message:Is this happening somewhere in the type traits code? Can you post an instantiation backtrace?
I guess the question here is: "should is_polymorphic<some_union>::value compile?"
If so, then we have a bug in is_polymorphic. If not, we should
change all uses of is_polymorphic<T> in
boost/python/class.hpp boost/python/object/class_converters.hpp boost/python/object/inheritance.hpp
to: mpl::and_<is_class<T>, is_polymorphic<T> >
You can make this patch yourself in Boost.Python as an interim
measure to see if it makes wrapping unions work.
I did it, but it didn't work. is_class<some_union>::value evaluates to true. 8/
I believe that is_polymorphic<some_union>::value should evaluate to false, since unions can't be polymorphic.
