Excerpts from Ertugrul Soeylemez's message of Tue Aug 10 03:40:02 -0400 2010:

Then you can only run evalCont, if r = a, which makes that function quite pointless:

evalCont :: Cont r r -> r evalCont = runCont id

Ah, yes, that was what I was imagining. I don't think the function is useless (though it is pointless ;-); it lets you transform continuation-style code into normal code. Also, r is usually not fixed (unless you use mapCont or similar), so it might be more accurately described as Cont a a -> a. Cheers, Edward
