Ah yes, thank you! Saying "It seems to me that if this were a class, the
implementor would be defining a traversing order by defining pull"
should have tipped me off to check out the 'Traversable' class before
asking (but, having probably only seen that class once or twice before
in passing, it was probably too deep in my head for quick retrieval).
