[section:has_nothrow_assign has_nothrow_assign]

   template <class T>
   struct has_nothrow_assign : public __tof {};
  
__inherit 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.

__compat 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".
