          Issue ID: 23377
           Summary: class method overloading with same name doesn't work
                    for base classes
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW

The compiler doesn't check the base class overloads when the correct overload
is provided, only on the base class, but contains an incorrect overload on the
derived class. If the derived class doesn't have any overload, it works. E.g.:

=================

struct Foo
{
    void foo(Bar b)
    {
        b.bar(this);
    }
}

struct Foobar {}
struct Foobar2 {}

class Base
{
    void bar(Foo f) {}
    void bar(Foobar2 f) {}
}

class Bar : Base
{        
    void call()
    {
        Foo f;
        f.foo(this);
    }

    // if you comment this it will choose the right overload, therefore it
works
    void bar(Foobar f) {}
}
