Well, it seems it'd be best for SQLObject to implement neither __len__
nor __nonzero__. Please somebody write a FAQ entry summarizing the thread;
add code snippets.
It inherits __nonzero__ already (so SelectResults are always true), but
does not implement __len__. Like I said, I really dislike those very
few instances where you might encounter objects you can't test an object
for truth, so I'm not very positive about that resolution. But I don't
know, that's really the only way to keep people from introducing bugs
into their code, since it's so natural (but probably incorrect) to test
a SelectResult for truthfulness.
