This is a pure-Rust crate for parsing/formatting [Python literals]. See the
[documentation](https://docs.rs/py_literal) for more information.

[Python literals]: https://docs.python.org/3/reference/lexical_analysis.html#literals

**This crate is a work-in-progress.** The goal is for the parser to support
everything [`ast.literal_eval()`] does, but it supports only a subset. See the
docs for the `FromStr` implementation for `Value` for details.

[`ast.literal_eval()`]: https://docs.python.org/3/library/ast.html#ast.literal_eval
