This code is currently arcane due to its wild evolution over the past years. I'll be reorganizing and writing docs.

This plaintext form is only an intermediate stage. Eventually, all this will be ASTs.

==================================

If you want to get a (very basic) idea of what the ASTs look like:

Running VIEW=true make test will dump trees as plain text in views/. If you have LLVM installed, you can see the generated IR in ir/. The actual native (binary) module serializations are put in mods/.

Good luck!
