The output of
type-inversion
is non-inflationary, as specified in the original mechanization using this reduction declaration:Solving the following theorems using
type-inversion
in Beluga would require complete induction. See https://github.com/Beluga-lang/Beluga/issues/227.https://github.com/MartyO256/mechanizing-standard-ml/blob/07d71cd2cbed485449235ad22075701c475b96dc/src/safety/regularity.thm#L2352-L2754
