I have lately been pretty bad at doing PRs, so I think you need @blishko to review. But I am actually liking it a lot. It is BTW possible to add tests to CLI stuff like this, via clitest.hs, it's something to consider, though it may be a little convoluted with this one.

Thank you, yes :) I think at the time we didn't have the . notation? So it was more useful. Much better this way!
