Re: [sv-ec] Proposal for extended syntax for extern methods of parameterized classes

I don't think that further restrictions are necessary since there
are already semantic restrictions that the extern must exist in
the same scope as the class declaration.  So <..>::<..>:: would
not be legal in any case.  I didn't deal with the specialized
form since that isn't restricted in the method form either (and
makes no sense in either context).  The "class_scope" prefix
is exactly what is currently done for the method name prefixed
form as well.  The other semantic rule suggestion applies to
the method prefixed form as well; if you'd like to suggest that
for both, that would be fine, but it isn't clear to me that it
is needed.
