Lisp with Java
I was very pleased with myself for finding Armed Bear Common Lisp; you've gotta love that name. You get a cool editor as well!! For someone like me who works in a mainly Java shop the excellent looking integration of Lisp and Java is cool and potentially very useful for prototyping (I wonder if Bill Clementson knowws about this?). (I'm also rather more attracted to building GUI's in Swing as Lisp is has so many different GUI libraries and many are rudimentary, only run on some platforms etc.)
Then it turns out that Lispmeister mentioned the latter 2 over 2 months ago and I missed it:Lispmeister.com : Lisplets
More to play with!!
PS: Yes, Bill Clementson does know about these !! Article in June or so; I wonder if he has done any more with any of them ?
