There are also enumerators and enumeratees. I think that

run an iteratee on multiple sources

second part from a String )
I would say more simply that an enumerator is a data-producer (or source).
Although it is a producer defined as a consumer (or sink) feeder.
Sure, but then why not define them as
type Enumerator a b = Iteratee a b -> IO b
? After all, I imagine a data producer to feed an Iteratee with tokens
until it has run to completion.
The reason for the definition
type Enumerator a b = Iteratee a b -> IO (Iteratee a b)
is that you can now concatenate different input sources.
