Using Rogers' characterization of acceptable programming systems, Rice's
theorem may essentially be generalized from Turing machines to most
computer programming languages: there exists no automatic method that
decides with generality non-trivial questions on the behavior of
computer programs. https://en.wikipedia.org/wiki/Rice%27s_theorem

H correctly divides inputs into
(a) Halting
(b) Not halting
(c) Cannot be decided by H
