@sagilio The comment itself is not affected by the model config. However, model config contents are necessary to test it. So I just add comments to an existing model config test file. Do you think that writing a dependent file to test the comments is better, or just keeping it is enough?

I think we need to write new example files and tests for the comments test, and the test also needs to cover the entire line of comments.

This will also more helpful to others format support in future.

1. Don't mess with the existing models. Try to fork a new model from RBAC and test all your supported comments on that file only.
2. Make sure to align with the Golang Casbin, you should NOT create a comment style that are not compatible with Golang Casbin's model. If you are doing so, try to get help from the community to let Golang Casbin support it first (or make PR to Golang Casbin by yourself if you know Go). Finally all Casbin implementations will support the SAME commenting style and Golang Casbin should be the first to support it, then port to others.

OK, I got it, I have signed this PR as WIP and will complete the tips above before requesting a merge.

@hsluoyz golang version also supports the inline comment: https://github.com/casbin/casbin/blob/5225b867429740e5ffdb69a124c3890f1a66a4f9/examples/comment_model.conf#L1-L12
