<h2>Overload Resolution</h2>

The function overload resolution mechanism in py_cpp works as

class is found which has a matching attribute, only functions overloaded
in the context of that class are candidates for overload resolution.

this sense, overload resolution mirrors the C++ mechanism, where a name
in a derived class "hides" all functions with the same name from a base
class.
<li>Within a name-space context (extension class or module), overloaded
functions are tried in the same order they were
<code>def()</code>ed. The first function whose signature can be made to
match each argument passed is the one which is ultimately called.
