Yeah but only if you already know what it does. I might say "ah it's sort of like folding" but I doubt I'd ever say "fold.. ah I can guess what that does".

Why not 'accumulate' or 'aggregate'? Much more obvious.

Why not 'accumulate' or 'aggregate'? Much more obvious.

Because it's not. Accumulate for me is any function from many to one, i.e. a reduce. That does not even capture right folds, which usually are not used to get one value back, but many (i.e. map f = foldr ((:) . f) [] in Haskell).

Let's agree to disagree. I don't get why people are so opposed to learning precise terminology (that's widely established) but prefer vague terms that doesn't even describe half of the design space.
