Hi! Could we have tests so it's easier for us to verify that it works as intended?
There are file-based tests in the repository. Every matchable pattern should be covered to illustrate how it's supposed to work.

There are 2 kinds of tests:

• positive - when linter should report something
• negative - when linter should not report something
  https://github.com/quasilyte/go-consistent/blob/master/testdata/positive_tests1.go
  You can add to the existing files or create a separate file

Hello, bro... I'm happy to help for each Open Source.
So, I'll add both positive and negative tests shortly - within a short time. It's seems easy for implement.

I've added the required tests - both positive and negative cases to cover the newly supported argument list types. Let me know if anything else needs to be adjusted. I'm ready to improve my PR.
