>Description:

>How-To-Repeat:
Suggest an option that warns if an enum variable or
parameter is assigned a value that isn't from that enum vis:

enum e1 { e1a, e1b };
enum e1 e1v;
enum e2 { e2a, e2b };
enum e2 e2v;
int i;
e1v = 1; // warning
e1v = e1a; // ok
e2v = e1v; // warning
i = e1v; // ok I guess
e2v = i; // warning
