Of course!  What can't you do in C++? :)

Yes, it is possible, see my other post.  However, I don't think it is possible
to have 'something' as a parameter.

Given that 'is_enum' is possible, and that 'has_key_something' is possible, you
can combine the two and make a 'has_key_something_that_is_an_enum'.
