From 898c915a31633b9df3294382c0499d2ebca4fb2f Mon Sep 17 00:00:00 2001
From: Guido van Rossum <guido@python.org>
Date: Thu, 4 Sep 1997 22:12:34 +0000
Subject: [PATCH] Added some try-excepts so that it can be imported in
 restricted mode (though some type names are undefined in that case, e.g.
 CodeType (inaccessible), FileType (not always accessible), and TracebackType
 and FrameType (inaccessible).
