Sorry for asking a question that is answered in the DWP - unfortunately a couple
of us are disagreeing about what the DWP says!

We know that a template global function can be specialized. We know that a whole
template class can be specialized. We also know that these specializations must
be declared before they are used.

Can an individual member function of a template class be specialized. If so, how
is it declared? Thanks.

DWP says the following: 

====
14.5  Template specialization                              [temp.spec]

1 Except for a type member or template class member of a non-specialized
  template  class,  the following can be declared by a declaration where
  the declared name is a template-id: a specialized template function, a
  template class, or a static member of a template; that is:
          specialization:
                  declaration
  [Note: a static member of a template can only be specialized in a #define-
  inition due to syntactic restrictions.  ] [Example:

====

Since a member function of a template class is none of the following:
    - specialized template function
    - template class
    - static member of a template

I would read this as saying that a member function of a template class
cannot be specialized.

Wonder why the restriction on template class members ...
