Re: [Haskell-cafe] A quick question about distribution of finite maps.

Thanks Tom! This is not a complete disaster theoretically, because a `mempty` map corresponds to a function with `Void` domain which may not be invoked anyway. But truly it makes the definition problematic, in the way similar to how `Set` is not quite a functor — usually it works but sometimes _map g ∘ map f_ may lose more elements than _map (g ∘ f)_. I am not sure how much of sad I should be about it. The function still works most of the time.
