(I'm sure I'm not quite so elite as that, in reality). If I really want a circular index, I know where the modulor operator is, and can write `lst[n%len(lst)]` if I am so inclined. If I needed this niche case as a frequent thing, I can easily subclass list to do the circular behavior. Signal processing is a perfectly good thing to do, but it's definitely a 0.1% use case... probably less in pure Python. If I actually want to do a convolution, I'm going to use NumPy, and know where `np.tile()` is. -- The dead increasingly dominate and strangle both the living and the not-yet born.
