The only other alternative is to introduce some kind of block. This is
a good solution that is not particularly intrusive; it leaves the door
open to a well-designed block structure later on. The one niggle I have
is that it's going to be a little unwieldy to explain, but people who
create properties really ought to understand Python well enough to deal
with it.
