I don't think SML-NJ is dead. It just seems that the homepage isn't updated very frequently. I had exchanged some e-mails with a few of the SML-NJ people last fall, when I was trying to port the interpreter and some of the e-mails suggested that they were working on getting anonymous CVS access going. I don't know if they have managed to or not, but it seemed to me that there was still development work going on.
I know that many people are actively using SML-NJ, so I doubt it is going away anytime soon.

Following the recent OCAML posts I bought Paulson's ML for the working programmer last week and tried to download SML/NJ. The web site at http://cm.bell-labs.com/cm/cs/what/smlnj/ was unavailable for at least 36 hours (its back now though).

Last time I checked the SML/NJ ebv. I found it very unfriendly, and not very fun. The Paulson book is pretty good however.

That was supposed to be env as in environment. Sorry.

Do you have a better suggestion than SML/NJ as an env? - and anyway why did you find it unfriendly?

Well what I used had a line mode interface, without even having the ability to go back to previous expressions, or to have seperate 'definitions' window etc. IIRC things are much better now, but I have no personal experience (I mainly use Scheme now, and as for FP I am playing with Haskell).
From what I heard OCAML has much better facilities, but I'll let others comment on that.

I am playing with Haskell
I've just (a minute ago) got my first Haskell program to work! I still don't understand everything I've typed... Have you tried debugging? I went about things in the wrong way - wrote a chunk (400 lines, including comments), got it to compile with ghc, and then wondered how to debug it. Monads become a problem when you want to insert a print statement in a function! Anyway, I've now seen the light - use Hugs to test out small chunks.
I am sitting looking at an image with three overlapping (semi-transparent) rectangles from the following code and feeling proud as a new father (well, maybe ;-)
testImage (x, y) = r + g + b
where
r | bar x y = RGBA 1 0 0 0.5
| otherwise = transparent
g | bar y x = RGBA 0 1 0 0.5
| otherwise = transparent
b | square x y = RGBA 0 0 1 0.5
| otherwise = transparent
bar p q = p>0.05 && p<0.2 && q>0.1 && q<0.95
square p q = p>0.15 && p<0.7 && q>0.15 && q<0.7
main = writePpm "test.ppm" 8 white 20 20 (0,0) (1,1) testImage

OK, this vicious and unsubstantiated rumour (who posted it?) has just been firmly denied by a (new) member of the SML/NJ team. I'd post a link to the appropriate c.l.functional article, but Deja isn't working at the moment.

Deja is being reincarnated which explains the problems I had linking to a post. They don't seem to have recent posts yet, unfortunately.
