Formula One is an experiment in ways to ergonomically build syntax trees and transformations in Rust.

The early development of this language is discussed on my blog in Lisp in Two Days with Rust
The language is a small subset of the LISP described in https://norvig.com/lispy.html. Notably it supports the following special forms:
(if <cond> <then> <elze>)for conditional evaluation of<then>or<elze>(define <sym> <expr>)binding a value to a symbol(<sym> <args>...)for calling a named function<sym>
All evaluation takes place in a single global environment. The language does not support user-defined functions with labda or the nested environments that they would entail. Quoting of values with ' or quote is also not supported. The parser recognises comments and whitespace but is yet to bind them to primary tokens as trivia.
This is only intended as an experiment to develop techniques for building syntax trees in code. It isn't intended as a production use language.
