Sure they do.

    C::T  foo;
    function C::T my_function(); ... endfunction;

Both would use the "T" from the default specialization of C
as the type.

The second is exactly the situation I posted originally -- when
you parse C::T you don't know if you are referring to "T" in
the default specialization of C or whether you are referring
to the unspecialized name "T" in the parameterized class
for an extern method definition.

And, as I also posted previously, you could require C#()::T
in such situations but that would be irregular with the
semantics of a reference to "C" in other type contexts.
