[IronPython] str, repr and getattr

[Sanghyeon Seo]

2006/6/8, Dino Viehland <dinov at exchange.microsoft.com>:
Thanks for the report.  We'll fix this for the next release.  The fix
is actually pretty simple (wrap the Ops.Call & return true in in
OldClass.cs in OldInstance.TryGetAttr w/ a try/catch
MissingMemberException, right after the 2nd TryRawGetAttr) if you want
to work around it until then.

In case that others have similar issue, here's a patch you can apply.
