Description

I get a lot of use from linters in programming python generally, such as pylint, flake8, mypy, bandit.

Would it be possible to provide linters for lark grammars, which would give suggestions on constructing good grammars?

Research direction
Investigate the Lark grammar format (e.g., examples in the repository) and existing linting patterns to propose specific linter rules. Review comments in the issue for any additional context or hints from maintainers. Since no detailed specification exists, the first step is to outline a set of potential grammar suggestions and then implement a proof of concept linter.
