From a layman's point of view, aren't structures like enumerators/iteratees
more suited to deal with IO?
Or maybe they just wouldn't apply in the case of GUI...

I haven't read the original Haskell School of Expression, did it use FRP
back then?

The original SOE had some FAL (functional animation) stuff, but I
don't think it used specifically the word FRP. Certainly the concept
of a first-class signal (behavior and event) was present.

Oh! I have a good, small (single-purpose; reusable), useful one!
A text field which tab-completes words or phrases from a dictionary.
Haskeline provides useful (non-FRP) for implementing this, but it
seems like FRP could handle this in an interesting way.
