generator libraries

[Mark Volkmann]

Many months ago I ran across a couple of libraries containing utility
functions for working with generators. I recall one was a "take" function
that was used to take only the first n values from a a given generator. I'm
having trouble locating those libraries now. I think one of them was
written by a TC39 member. Can anyone point me to a library like that?
