<P><FONT SIZE=2>FYI, for those inclined to take a look, or anyone willing to apply a patch to ZCatalog.Lazy:<BR>

<BR>
This bug affects svn HEAD, Zope 2.10.x, Zope 2.9.x.<BR>
<BR>
LazyCat.__repr__() calls __getitem__() in such a way that __add__() functionality is crippled (see collector issue) - causes AttributeError. The problem can be worked around in LazyCat.__init__(), which is what the diff/patch attached to the issue does (does hasattr() check and works around appropriately if lazcat doesn't have '_seq' attribute).<BR>
<BR>
Any comments/thoughts appreciated. If this looks good, can someone with commit abilities check this in?<BR>
<BR>
Thanks,<BR>
