Could the binary AST be...a bit more binary? #72

I'm revisiting this proposal a few months later, and I'm wondering: could this proposal be better specified in terms of raw bytes? Currently, it seems largely spec'd in terms of a JSON-like format, but IMHO that doesn't really seem like it's as small as it could be. For one, it could leverage LEB128 much like WASM does and in a similar fashion. It also doesn't need to keep type names or even operator names as strings, so I feel being a bit more binary could realize the proposal's intent a little better.

We're working on the serialization format separately. It's not ready for proposal yet, as we've been trying a number of very different techniques.
