Approved.

Reraised as an issue

Apparantly not at all... looks like this was from 3.0, I had just never noticed it. That just seemed to be the page with the most detail.

You linked to "proposals", is this still in beta?

does not work in general as the exponent of a cannot be a constant but depends on b. This could be remedied by something like ceil(log2(b)) instead of 10.

Map Max: Fury Road

• There should be more random tests (~ 100). Random tests shold always cover both valid and invalid (no path) cases.
• Returning different types (list/bool) is bad practice. When there isn't a path the function shopuld return a "no-value" (None in python) or raise an exception.

The assertion messages should provide information about what was wrong (see the docs).

As dfhwze noted, this isn't likely to be approved, but it's good to know for another kata.

fixed there

Lots better, thanks.

I changed the Show instance in preloaded, let me know if that works better.

In Haskell, the Crates add frustration only.

Please can the Show instance make them transparent? The current instance maximises visual clutter, with the useless color accessor.

Approved. This looks great! Thanks for your work on this.
