Overloading is having a different parameter list, not different return
values. Here, you have the same parameter list, so the compiler generates
the same signature. That's why the error.

You should have only one operator, which returns the actual type of m_n. It
is up to the user of the class to cast it. This way, you ensure that the
end-user knows that he's casting, and knows that he can get into trouble
that way.
