The Twisted Deferred object is a quasi-standard when doing asynchronous
programming in Python.
The only seriously competing approach AFAICT is generator-based syntaxes
(which Twisted also provides on top of Deferreds by the way).

Inventing a third idiom just for taste reasons doesn't sound very
reasonable. Of course, if the third idiom turns out *really* better in
terms of expressiveness then why not.
