For me, a good reason why one should look at Haskell is because you should NOT look at Haskell since it will change your view on programming so much, you don't want to go back... ;-)
But where is the great IDE Haskell deserves??? :-) Seriously, 99% of the programmers I know don't want to look at it because when they see Emacs or VIM, they say "what the f*ck????, I don't want to go back to the stone age". If you want to attract more people that are inside the "imperative-OO-with-nice-IDE-blob", create a great looking and functional IDE. An IDE that integrates the existing tools. That shows you graphical pictures of the graph rewriting process, potential space leaks, profiling bottlenecks, etc. Heck, why not introduce pictures as symbols and values, as in DrScheme. Or UNICODE fonts. or or ... Okay, enough of that, off topic ;-)
It has been suggested we could just sit DrScheme in front of ghc/ghci. Anyone with experience who'd like to step up for this? -- Don
