Another type_traits question

Does anyone know of a way to detect at compile time whether a type has a
publicly-accessible copy constructor (without generating an error)? It seems
as though the sizeof/overloaded function technique might hold some promise,
but nothing I've tried so far seems to work.

TIA,
Dave
