New I did find that interesting. One major complaint down.
The fact that it is ugly isn't a new complaint. Java generally is ugly, I expect that.

Cheers,
Ben

New You'll find this interesting too - Bistro
[link|http://bistro.sourceforge.net/overview.htm|http://bistro.source....net/overview.htm]

Its a preprocessor that provides smalltalk-ish syntax and capabilities on top of Java. It generates inner classes for the closures. Its been around for at least 5 years. More of a proof of concept than a practical language - there's no debugger support or anything. But the paper is interesting.

Also, FWIW, Squeak doesn't have proper closures out of the box - it has BlockContext's instead which also don't do a good job of hanging onto local variables properly (there is a workaround you can use but you have to send the thing a message fixTemps to ask it to hang onto the temp vars).

There is a closure implementation done for Squeak, its waiting to be adopted. I think it will end up in there eventually.

         Simple explanation: - (admin) - Feb. 14, 2005, 08:13:23 AM EST
         Wheras an "outer" class is just an ordinary class. -NT - (CRConrad) - Feb. 14, 2005, 10:26:56 AM EST
         There's some other types as well - (ChrisR) - Feb. 14, 2005, 11:44:54 AM EST

                 You misunderstand, on at least one issue: - (CRConrad) - (1) - Feb. 16, 2005, 09:23:42 AM EST
                     No, they can be used as factories as well. - (admin) - Feb. 16, 2005, 09:41:31 AM EST

                                 Is it just interesting, or is it useful? - (pwhysall) - (2) - Feb. 16, 2005, 03:34:25 PM EST
                                     Well, in Java it's pretty useless. -NT - (ChrisR) - Feb. 16, 2005, 04:02:59 PM EST
                                     It's a pretty basic feature found in functional languages - (jake123) - Feb. 16, 2005, 05:16:04 PM EST

                                 I understand it! - (ben_tilly) - (3) - Feb. 17, 2005, 10:24:40 PM EST
