That, of course, assumes that you really can perform the right
dispatching. For example, when dispatching from Python to C++, there
might be tricky issues, such as how to relate the many C++ integer
types to the two Python integer types. Some languages (e.g. C++) even
allow to define functions with a potentially unbounded number of
overloaded definitions (i.e. templates).
