It's perfectly possible that you don't yield a deferred but your code is still correct. E.g. let's say that you want to wait on three ops but you do want them to execute in parallel, then d1 = f() d2 = g() d3 = h() yield gatherResults(d1, d2, d3) is totally a thing :-) yield in @inlineCallbacks just means "pause execution and resume when this deferred fires". hth lvh
