Also, a less forgetful version of subs might be useful:

     withSubs xs e :: [a] -> Event b -> Event (b,a)

and then

    subs xs e  = snd <$> withSubs xs e

or, if you like,

    subs = (fmap.fmap.fmap) snd withSubs

Btw, you can read the three fmaps directly from the signature of withSubs (two arrows plus one Event on the way to the pair).

That's a cute trick with the number of fmap's required.  Never thought of it that way.

Also, I'd like to apologize for not mentioning quicksilver from #haskell in my last e-mail.  An honest slip-up, but an inappropriate one.
