Yeah, I saw that article too... but I'm not sure I really buy it. Development time is okay and all, but how about maintainability? I want to see these guys write a 500,000 line lisp program and come back to it 5 months from now, and then maybe they'll wish they'd have used Java. I'm not sure execution is quite as big of an issue as it once was. Scripted languages pay for an overhead in loading and such but for a language such as perl which usually runs off the command line, this isn't all that noticeable. Hell, a lot of compiled languages tend have so much stuff thrown in that they the computer ends up spinning it's wheels just loading unnessary junk. All in all, I'd rather shoot myself before I'd start programming in Lisp (lets just say I was scarred for life in college and leave it at that.)
