Parakeet is an object-oriented Forth-like stack language for the Parrot VM. It is written in PIR and compiled its code directly to PIR. Parakeet lets you do logical, numeric and string operations and comparisons, conditionals and loops, define variables, functions, classes methods, create instanciate and call methods on objects.
Parakeet is Forth-like, but not anything like "standard" Forth, it is very machine specific to Parrot, building directly upon Parrot's machine semantics, not on those of late-80s micro-processors. Parakeet, for example, provides no words '@' and '!' as "direct" access to "memory" does not exist in Parrot. Data is stored and retrieved by holding references to objects like in many other OO languages.
0.3 is a major rewrite over previous versions of Parakeet. In particular, the code is much leaner now due to me removing a key design stupidity in my inline code generation. The entire language, README, and test script gzips into less than 10K.
Parakeet is to the point now (I hope) where people can use it to experiment with and experience Parrot from a different perspective. The interactive PIR and opcode tracing is a particularly effective way of playing almost directly with the Parrot VM. To start playing with an interactive Parakeet interpreter, unzip the tarbal somewhere where parrot can find the 'parakeet.imc' file execute that file with the Parrot interpreter.

Should it go into CVS abd being included in 0.1.1?
If no one else has any objection that would be fine by me, it would encourage more people to try it out. I presume I would update it by sending you patches?

That means there's no "end" opcode in the PIR that's being dynamically compiled. The compile opcode expects a return value (success/failure) -- an int.

I've been really behind on my mail, but this is cool, and thanks a lot.
If you want it in parrot's CVS tree it can go in -- I'm fine with that, and we'll get you CVS access to do so. (Unless I'm really behind, in which case it's in and you've got it already, which'd be cool -- Dan

Thanks! Right now I'm actually working on some ideas vis a vis making Parakeet work with modular core word sets (using "code <word> <pir> next", so it can be a standard Forth interpreter also by loading a different wordset at startup.

Restricted CVS access would be great. Do you need an ssh key or something?
