template <class T>
struct has_nothrow_assign : public true_type-or-false_type {};
Inherits: If T is a (possibly cv-qualified)
type with a non-throwing assignment-operator then inherits from true_type,
otherwise inherits from false_type.
Type T must be a complete
type.
Compiler Compatibility: If the compiler does not support partial-specialization of class templates, then this template can not be used with function types.
Without some (as yet unspecified) help from the compiler, has_nothrow_assign
will never report that a class or struct has a non-throwing assignment-operator;
this is always safe, if possibly sub-optimal. Currently (May 2005) only Visual
C++ 8 has the necessary compiler support to ensure that this trait "just
works".
