I thought that plan was from_iterable and/or from_numpy?

• API: io functions for v2 #2116

At the very least, could we change the spelling to match where the term originated?

yeah just struggling to think of a good name

if from_iterable doesn't come with any unexpected implications (which I can't think of), that's probably fine
