recently i was looking through frshmeat.net and found this fun little language The Squirrel Programing Language its a very small (around 6000 lines of code).
(taken from the front page)
Squirrel is a high level imperative/OO programming language, designed to be a powerful scripting tool that fits in the size, memory bandwidth, and real-time requirements of applications like games. Although Squirrel offers a wide range of features like:

Open Source zlib/libpng licence
dynamic typing
delegation
higher order functions
generators
cooperative threads(coroutines)
tail recursion
exception handling
automatic memory management (CPU bursts free; mixed approach ref counting/GC)
both compiler and virtual machine fit together in about 6k lines of C++ code.
optional 16bits characters strings
Squirrel is inspired by languages like Python,Javascript and expecially Lua(The API is very similar and the table code is based on the Lua one)

i really like how it handels objects (much better than in java)

its fun give it a shot. does anyone know if it will compile under MOS?

this has been "Poundsmack's Random Thoughts for the Day" (that should be a new forum) hehe

How about Haifu instead?

It's (afaik) the world's first Haiku Structured programming language

There doesn't seem to be no source code for compiler, but the idea can only be described as... indescribable

Don't forget Rebol, the great language of amiga-legend Carl Sassenrath!

(ok, a bit oftopic, but I had to mention it )

rebol = awesomest
