Calls to "check" will always return a decision object and the authorization error (if any) can be accessed within expressions using the new decision methods "errored" and "error".

Turtle replied; `and then the different branches of Arithmetic--
Ambition, Distraction, Uglification, and Derision.'

  `I never heard of "Uglification,"' Alice ventured to say.  `What is it?'

  The Gryphon lifted up both its paws in surprise.  `What!  Never
heard of uglifying!' it exclaimed.  `You know what to beautify is,
