Probably even more permissive. The rule of thumb is that the overriding
function must not hijack any other in the base class. Consider:

class Base
{
    void foo(int);
    void foo(string[string]);
}

class Derived
{
    override void foo(int);
}

This should go through because there's no chance I could pass an int and expect
the overload taking a hash to kick in.
