One way to approach it is to say that -std=c++0x is an evolving thing,
containing experimental features that may not be available in future
versions of GCC. Then when we figure out what 'x' is (probably '9';
Bjarne says we can't use hexadecimal), we add -std=c++09 with the
features that actually made it in.

True :(

Granted, there's a bit of low-hanging fruit we could pick, just to get
the gears turning. static_assert comes to mind...

I'm all for it.
