> "sequence must be a sequence"

The subtle minutiae of aficionados necessary to interpret the meaning of those two words in their distinct relation is opaque to a new comer and doesn’t serve the widest possible audience usefully to get the job done quick. The second placed sense has a range of possibility narrower than iterable as has been said, all sequences are iterables but not all iterables sequences.
