           Summary: Should report function modifiers in from as errors or
                    at least warnings

Functions modifiers in front of the function should be reported as warnings or
even errors.

class X {
    const int* f() { return null; } // should give a compiler warning
    int* g() const { return null; }
}

In the above code it is too easy to confuse it with const(int*). This is VERY
unreliable and should be warned loudly when somebody does this.
