Comment (by goldfire):

 And also, I thought of this: what type would `Bool` have? It surely must
 have type `*`. But then would it not work as a kind anymore? So perhaps
 this isn't really such a good idea. In any case, I don't believe there is
 any serious consideration of implementing Reid's plan... just musing about
 alternatives.
