I haven't seen it mentioned in the discussion here, but in C++11, the
definition of is_modulo was clarified as:
"True if the type is modulo. A type is modulo if, for any operation involving
+, -, or * on values of that type whose result would fall outside the range
[min(),max()], the value returned differs from the true value by an integer
multiple of max() - min() + 1."
Do people have objections to switching numeric_limits<signed>::is_modulo to
false (setting it to true when -fwrapv is used can still be discussed
afterwards)?
