As I am learning the source code, it seems to me that python's pattern matching is not supported at all.

We have a visitor ready: https://github.com/charliermarsh/ruff/blob/c7349b69c12b7511d48fc45390eac8d7282062a5/src/ast/visitor.rs#L527-L571

But, that's about it.

Things to support (feel free to update):

• Unused variables check
• Variable names check (MatchAs pattern)
• Custom rules, like do not match floats
