In a switch() statement that takes an enum-class type, code completion on the 'case' shows the possible enumerators, but doesn't include the enum name for scoping, so the resulting code doesn't compile.

Example:

enum class Color {
    Red, Yellow, Green, Blue
};
void foo() {
    Color x;
    switch (x) {
        case //complete here
    }
}

The code completion shows 'Red', 'Yellow', 'Green' and 'Blue' as options, but doesn't include the Color:: part, leaving 'case Red:' which is invalid for strongly-typed enums.
