From 2b83b4601f9f588b46667b541b100b5924019a14 Mon Sep 17 00:00:00 2001
From: Fred Drake <fdrake@acm.org>
Date: Thu, 3 Aug 2000 17:43:02 +0000
Subject: [PATCH] Remove the tp_print handler. Revise the tp_repr handler to
 produce a more "minimal" presentation. Make the tolist() method use
 PyArg_ParseTuple() and provide a docstring.
