As of 8.2, it doesn't appear to work properly yet.
It looks like the top level qualifs on the return type aren't being ignored
if the return type is sealed in a typedef or __typeof.
typedef int const ic_tp;
int const f(); //ignores the const here
ic_tp f(); //breaks because the const isn't ignored here
Same with:
int const f(); //ignored here
__typeof(int const) f(); //not ignored here
