         this sense, overload resolution mirrors the C++ mechanism, where a name

         <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.

+        This means in particular that you cannot overload the same function on 
+        both "<code>int</code>" and "<code>float</code>" because Python 
+        automatically converts either of the two types into the other one. 
+        Thus, if the "<code>float</code>"-overload is found first, it is used 
+        also used for arguments of type "<code>int</code>" as well, and the 
+        "<code>int</code>"-Version of the function is never invoked.
