Your reply reached the mailing list a bit mangled, could you please
clarify?
If the default argument isn't dependent on other template parameters,
we can check immediately whether it is a suitable template argument
for its parameter, including being a constant expression.
Just wanted to add that we should indeed do this also to catch things like:
struct blah { int member; };
template <char param = &blah::member>
class template6_blah;
which currently we are also missing.
