Nice idea making your synchronous code work like this too.
Have you considered using the @inlineCallbacks decorator instead? I bet
you could make that work too, you could write your own decorator that
uses inlineCallbacks or something synchronous, then the above becomes:
@cleverInlineCallbacks
def get_foo(arg1, arg2):
args = prepare_request()
result = yield make_maybe_blocking_call()
do_stuff(result)
finalValue = do_more_stuff(result)
defer.returnValue(finalValue)
Which can be a lot neater when you get stacks and stacks of callbacks.
Python's lack of a block construct otherwise makes that really unpleasant.
Cheers,
Doug.
