There was a problem hiding this comment.
I wanted to add a couple comments, like here and here, but the v8 coverage provider would mark the comment lines as uncovered for some reason I could not figure out (might be just a bug in the v8 reporter).
In #107 I experimented with switching to istanbul as coverage provider, but it seems to have other issues (marks import statements as uncovered) and the overall coverage metric drops considerably. So leaving like this for now.
