Template specialisation of template class member function

[GNiewerth]

Not necessarily. You can define a default template for something like Is_Pod where the falue is 'false', then specialise the template for POD types. When you use it for a new class or structure type it will automatically acquire the 'false' value.

Hehe, yes, I´m aware of that. But to use the power of memcpy you have to provide a type_traits specialization for your class.
