This compiles with no errors, but maybe it's better to refuse (and show an error) when a label has the same name of a variable:


enum int FOO = 1;
int main() {
    goto FOO;
    FOO: return FOO;
}


That helps keep code tidy, and also helps to avoid probably wrong code like (note the missing 'case'):

enum int CONST1 = 1;
enum int CONST2 = 2;
void main() {
    int x = 1;
    switch (x) {
        case CONST1:
            break;
        CONST2:
            break;
        default:
            break;
    }
}


Something similar toi the second situation is present among the Semantic Errors of Java code in the Google Web Toolkit too:

So far in my code I have never had a bug caused by this, so I consider this low-priority.
