Twisted supports this.

help("twisted.internet.defer.waitForDeferred")

example usage is:

@deferredGenerator
def thingummy():
  thing = waitForDeferred(makeSomeRequestResultingInDeferred())
  yield thing
  thing = thing.getResult()
  print thing #the result! hoorj!

With the new generator syntax, it becomes somewhat less clunky,
allowing for the syntax:

@defgen
def foo():
   somereturnvalue = yield SomeLongRunningOperation()
   print somereturnvalue
