If this were going forward as part of the standard I would say yes call in
"static_assert" and place it <cassert>, either as a regular macro, or as a
core language extention (depending how the vendor sees it).

However, there is a problem with your approach wrt boost:  how does the
static_assert function you've defined above, convert the bool parameter to
a static assertion (as an integral constant expression)?
