That's reasonably nice, although I'm not sure about the
name "propset" -- it sounds like a repair kit for an
aircraft. Maybe something like "setproperty" would be
better.
But there's something that bothers me about the whole
propery mechanism -- there's no straightforward way for
a property accessor to call the inherited version from
a base class.
Wrapping property accessors up in decorators makes this
worse. At least when the accessors are declared as separate
functions you have a chance of grabbing an inherited one
and calling it. But if they're buried inside property
descriptors with no other reference to them, it's a lot
harder to get hold of one.
