Lots of us are working hard to see that we do indeed reach compliance.

That may or may not be true.  Jason said that it is not easy, and that
is true.

On the other hand, neither are member templates, global common
sub-expression elimination, or a new standard library.  The first two
projects are complete, to a reasonably strict definition of complete,
while the third is well underway.

We have too many such stop-gaps already in g++.  We really don't want
to add additional language extensions at this point, IMO.
