variant_copy() is completely defined. Eric's concerns about
memcpy was that is undefinded.

Stop kidding yourself, variant_copy is much more predicable
than new T() that variant is using to provide basic guarantess.
Theretically, if a copy constructor crashes the memory
heap could already be corrupted.
The stack solution is much more safer in this respect
and it provides strong guarantess.
