In this particular case, Richard, I don't think so. The Block class is
an application-level wrapper for a graphical object. I don't want to
worry about zero-size objects. ("Is this column really empty, or does it
contain one or more zero-size blocks?") If you're interested, take a
look at "BlockHead" at www.jjposner.net.
BTW, from the (admittedly few) responses to my original post, it seems
there's some sentiment that "conditional expressions" are a non-Pythonic
misfeature. Interesting ...
