// C++ [expr.const]p1:
// In several places, C++ requires expressions that evaluate to an integral
// or enumeration constant: as array bounds, as case expressions, as
// bit-field lengths, as enumerator initializers, as static member
// initializers, and as integral or enumeration non-type template arguments.
// An integral constant-expression can involve only literals, enumerators,
// const variables or static data members of integral or enumeration types
// initialized with constant expressions, and sizeof expressions. Floating
// literals can appear only if they are cast to integral or enumeration types.
