I find this a bit awkward, and maintain that it would be nice to have this as a built-in language construct to do this natively. You have to admit:
smooth_signal = [average = (1-decay)*average + decay*x for x in signal
Is a lot cleaner and more intuitive than:
dev compute_avg(avg, x): return (1 - decay)*avg + decay * x
The proposed syntax strikes me as confusing and mysterious to do something I do only occasionally. In contrast, itertools.accumulate() is straightforward and far more general.
Definitely -100 on the proposal.
