I'm also sure the docs will say "Returns the first item yielded by the iterable." That last word is a dead give-away on how the choice will be made on any collection, Sequence or not. 😉 (Doubly true if this goes into itertools.)
The docs for more_itertools.first say it’s equivalent to next of iter, which makes the behavior even more obvious to anyone who understands iteration in Python, even if they’ve never used itertools before.
