Anything which works... I don't really care which version is used.

I'm currently using Squeak 3.10, but I can easily move my code to Pharo.

Excellent.

I'm going to be making some changes to the compiler:

* Accept $. in literal names so that namespaces will work.
* Make it use my own implementation of IRBuilder.
These two changes are minor and SecureSqueak specific. I'll need to
investigate tool support for keeping a "branch" of the new compiler while
still being able to commit fixes back to you.

I'll be integrating IRBuilder and all the compilation steps after it as a
core part of SecureSqueak. "Class" will be modified to store IR as well as
bytecodes. IR will be used to move CompiledMethods across the network in a
way that doesn't depend on the VM implementation or bytecode set.

I'll also be making changes to the debugger, but this might mean making a
fork of the debugger which is incompatible with Pharo.
