Goal: a library that extends nom to provide better tools for text formats (programming languages, configuration files).
Recognizing line and column in input data: nom-locate
Using nom-supreme
parsers need to be fault tolerant: recovering from the current error allows parsing the rest of the file: https://eyalkalderon.com/blog/nom-error-recovery/
We should also allow for various error levels (like warnings, that would not stop compilation)
precedence rules can be annoying to write
- precedence support: rust-bakery/nom#1362
most language parsers end up calling themselves recursively, resulting in stack overflow issues
if we have error spans, we should be able to display more context, like rustc's errors

should we support multiple phases, with &str -> Vec<Token> functions followed by &[Token] -> AST functions?
