I'll merge this along with the query-representation update when that arrives. 😉 It's perhaps minorly breaking since the show instances have changed (for the better).

Thanks!

I've changed query representation and fixed appropriate tests.

I only wonder If we want to differentiate between empty query (Just (Query Nil))) and completely missing query (Nothing)? Do you think that this difference could be semantically important?

[paluh]

I think that you should ignore my previous comment about query representation... I think that we really want to be exact here and reflect given url as close as possible in our values (so we want to catch this difference between missing and empty query). Am I right?

Yeah I think the distinction would be good to have. I'm not sure if semantically it would matter, but I guess the "visible" difference would be in the case of Just (Query Nil) you get a trailing ? on the URL.
