          Issue ID: 21862
           Summary: Taking address of non-static method without "this"
                    should not be allowed

This should *not* compile, &S.m needs 'this' which is not available there:

    struct S {
        int m(int x) {return x;}
    }

    void main() {
        int function(int) func = &S.m;
        writeln(func(5));           // does not print 5!
    }
