I believe decorators are in large part responsible for that. A callable
object does not work
as a method unless you define a custom __get__, so in decorator
programming it is
often easier to use a closure. OTOH closures a not optimal if you want
persistency
(you cannot pickle a closure) so in that case I use a callable object
instead.
