Detailed Description

Mechanism to opt-in for enum bitwise operators.

For an enumeration type T to opt-in for bitwise operators, there needs to be a declaration of a function

void enum_bitops_enable(T)

available for the argument-dependent lookup (the function is never actually called, thus no definition is required and no code is generated).
