Getting started with conduit, and I noticed that in Data.Conduit.Util:
Utility functions from older versions of conduit. These should be considered deprecated, as there are now easier ways to handle their use cases. This module is provided solely for backwards compatibility.
Of particular concern to me is zip :: Monad m => Source m a -> Source m b -> Source m (a, b). This seems pretty useful to me - I could independently work on a way of producing as and a way of producing bs, then just zip them together when I need them, rather than have to mix concerns earlier in the process.
But, like I said, I'm new in the ways of conduit, so I'm ignorant. What are these "easier ways to handle their use cases"?
