Bug 23384 – Suggest calling matching base class method when hidden

struct A {} struct B {} class Base { void fun(A a) {} } class Derived : Base { void fun(B b) {} } void main() { Derived d; d.fun(A()); } The above code (rightly IMO) produces this error: overloadhiding.d(18): Error: function `overloadhiding.Derived.fun(B b)` is not callable using argument types `(A)` overloadhiding.d(18): cannot pass argument `A()` of type `A` to parameter `B b` This sometimes gets reported as a suspected compiler bug, e.g. bug 23377 (closed as WONTFIX) or on the forum. After the error message for Derived.fun(A), the compiler should add an informational message when the base class has a match, explaining that match is hidden. That would help the user know the workaround and also make it clear the error is by design. (I had a look but I'm not sure how to implement it).
