Re: [Haskell-cafe] The C Equiv of != in Haskell miscommunication thread

i would just like to say thank you for all the extensive replies. after fiddling with them for an afternoon i'm positive i grokked the concept. it's just too bad the nice wrapper concept from [1] does not seem to be directly applicable to fix in haskell, since they require untyped side-effects.... anyhow, this has been very instructive. thanks again! v.

This thread should end, guys. It is inappropriate for the Haskell lists, and appears to have been a simple misunderstanding anyway.

Thanks everyone. Please stay friendly!

P.S. Have some cute code:

Control.Monad.Fix.fix ((1:) . scanl (+) 1)

Speaking of cute code, I'm fond of this:

map length . List.group . Control.Monad.Fix.fix $ show

And other (longer) variations which generate only powers of two. It's a great conversation starter for teaching about fix.
