Hmm, so is the list meant to be exhaustive?

5.19/1 enumerates where C++ requires a constant expression:
"In several places, C++ requires expressions that evaluate to an integral or
enumeration constant: as array bounds (8.3.4, 5.3.4), as case expressions
(6.4.2), as bit-field lengths (9.6), as enumerator initializers (7.2), as
static member initializers (9.4.2), and as integral or enumeration non-type
template arguments (14.3)."
To this list should be added: "as a static_assert (7.0)."
