Hum, an acceptable solution would be to give an error, asking to
explicitely asking to fully qualify the name :
void fun(int c = 0) {...}
void main()
{
int c;
fun(c=5); // error, ambiguous qualifier "c"
fun(main.c = 5); // ok
fun((c=5)); // ok
fun(fun.c = 5); // ok, but different meaning.
}
But still, raising an arror is not backward compatible.
