Even with warnings this is just terrible. People need to stop inventing languages where "False" is true, or an empty container is false or other insane "coercions" of this kind.

True is true, and false is false, if you're wondering whether this Doodad is Wibbly, you should ask that question not rely on a convention that Wibbly Doodads are somehow "truthy" while the non-Wibbly ones are not.
