According to 7.7 [expr.const] paragraph 1,
In particular, except in sizeof expressions, functions, class objects, pointers, or references shall not be used, and assignment, increment, decrement, function-call, or comma operators shall not be used.
Given a case like
enum E { e }; int operator+(int, E); int i[4 + e];
does this mean that the overloaded operator+ is not considered (because it can't be called), or is it selected by overload resolution, thus rendering the program ill-formed?
Rationale (April, 2005):
All expressions, including constant expressions, are subject to overload resolution. The example is ill-formed.
