[cfe-dev] Clang getting involved

FWIW: Clang supports Microsoft's __if_exists extension when in VisualC++ mode:
<http://msdn.microsoft.com/en-us//library/x7wy9xh3.aspx> It is similar (although
more restrictive) to "static if".

I'm not sure if a clang-specific language extension would be accepted into clang,
although it could be used to evaluate the usefulness of "static if". But then
I'm biased as I'd very much like "static if" to become part of the C++ standard;
even though it's viral, as Stroustrup writes, it would reduce the need for helper
templates.
