Maybe, except that POST is for DBC, and is expecting you to return
a boolean value. I have no idea who will call the POST block when,
if you put it on a class. It might be called after every method
on every object, given that people will probably intend it to be
taken as an invariant that must always hold for the class.
So what you really want is LEAVE. Except that probably fires off when
the role closure is left, rather than the class closure. Remember that
things like POST and LEAVE are officially properties on the current
block, not methods. And in fact, they aren't properties in themselves,
but merely add their closure to a queue that is stored in a property,
which probably ends up getting called internally with a .LEAVEALL or
some such, if there's any method name involved at all.
