struct S
{
    size_t foo()
    {
        size_t nested()
        {
            return value + 1;
        }
        return nested();
    }

    size_t value;
}

enum s = S().foo();

It seems as if checking callers in ThisExp::interpret would work.

    while (istate && !istate->localThis)
        istate = istate->caller;

Errors for a wrong 'this' will/should be detected during semantic.
