Declares that \var{function} should be used as a ``reduction''
function for objects of type \var{type}; \var{type} should not a
class object. \var{function} should return either a string or a
tuple. The optional \var{constructor} parameter, if provided, is a
tuple containing two or three elements.
The optional \var{constructor} parameter, if provided, is a
callable object which can be used to reconstruct the object when
called with the tuple of arguments returned by \var{function} at
pickling time. \exception{TypeError} will be raised if
\var{object} is a class or \var{constructor} is not callable.
See the \refmodule{pickle} module for more
details on the interface expected of \var{function} and
\var{constructor}.
