Thanks Martijn -- that works fine!  At the risk of sounding dumb, I don't
quite understand it -- why does the 0th array element within object
'site.css' contain a pointer to the object itself and how would a Zope
developer know this?  I've been thru the Zope source and haven't
come upon that particular construct.

And naturally, what resides at other offsets?  Oleg Broytmann wrote that
doing the say with offset 1 would result in a call to the object ???
