Hi @EFord36 ,

Thanks for spotting this, and thanks for the suggestions

Definitely looks doable, I'd welcome a PR, but I'll also have a look at this and see what I can do

Ideally I'd really like to be able to disable checks with comment directives. I haven't been able to pull it off yet, as far as I can remember It looked a whole lot harder to do with an ast than it is to do when working with a tokeniser. Seems I've forgotten about implementing this, but I'm going to have another look.

Cheers!
Stephen

@EFord36
I've implemented an overload check, and I'll push another commit for a disable comments feature
Can't say it'll be perfect, but it's pretty well tested
If it doesn't behave as expected I'd really appreciate if you opened another issue, any time
Thanks mate!
Stephen
