Can `implements` be called on a module instead of a class?

[PikachuEXE]

The example class Animal seems useless (for creating objects)

Also would be good to have example for "multi-inheritance"

module Hunter
  extend Behaves

  implements(:hunt)
end

module Prey
  extend Behaves

  implements(:run, :hide)
end

class Shark
  extend Behaves

  behaves_like Hunter
  behaves_like Prey

  # Something something
end

👋Hey thanks for opening this issue! Yeah I think it already supports Module though, can you verify that?

And thanks for the great idea! I've just added that into the README :)

I think it can be used
But I can only see error on exit, not on load (which is why #12 might be useful)

Also another (not very big) issue: calling behaves_like would cause duplicate errors
