The throw_exception() function template now throws an exception of
type that derives the type used to instantiate it, and this doesn't
work for non-class types. I admit that I completely missed this case.

My recommendation is to change the throw_exception() documentation to
specify that it must be used with objects of user-defined types. The
alternative solution is to fix the "bug" in throw_exception() and
allow non-class types, but that would disable the exception_ptr
functionality for these exceptions (on platforms without compiler
support for it.)
