Tcl and Awk were my prototyping languages of choice for the past 10-15 years. Before that it was Forth and a little bit of Lisp.
However, I have found that I have five criteria for such a language now. The first three are firm, the last two are desired qualities:
- Supports concurrency (lots of little processes/tasks) seamlessly.
- Seamless support for Bignums. I don't want to think about silly limitations of native word sizes.
- No fencing in (multi-paradigm support is a must!)
- Interactive. I don't want to do a edit/compile/run cycle for simple things.
- Portable. I want to install it everywhere.
Logo is nice, but has too many incompatible variants. StarLogo meets #1, but it looks too busy (especially StarLogo TNG).
Item 2 sounds a bit ridiculous, but for languages that aren't bound by performance needs, I don't see why I should be trapped in 32/64 bits. I'll never forget the time, back in 1984, when I typed (fact 120) in Lisp.... oooh.
I've been meaning to learn Mozart/Oz ever since I read CTM a few years back. It's a wonderful book. Maybe if I concentrate *real* hard and drop my other CFT projects, I could pick it up again. :-)
