Have you considered using an attribute (rather than a flag) for storing
the constexpr specifier?

Using attributes was previously suggested as a better alternative:

http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20110124/038124.html

There they were talking about the `final' and `override' keywords, but
the same arguments should apply to the constexpr specifier too.

Cheers,
Enea.
