I don’t think that actually is a problem, just an idiom

I should probably added more details and a repro, but it was an error indeed, I just can't recall :/

Found it on nubank's slack: the problem was that our clojure->dart custom lib expects ns with dashes and not underlines, so more like a convention indeed, not a real compilation or something problem. Even so, I do think this should be a warn linter, we can argue if should be enabled by default, but I think it's a common convention in clojure projects use dashes and not underlines for ns name

ok agreed, just a convention
