Bug 10688 – Misleading error message when attempting a "private override"

class Bar: Foo { private: override void func() {} } This doesn't compile and print "cannot override a non-virtual function". It took me a while to realize that the problem (in a larger class) was not in the base class, but in the attributes of the override. What about error messages like: "cannot reduce visibility of override" or "overrides must not be private"
