type SQ = SBV Q

Symbolic version of the type Q.

f :: SQ -> SQ

Declare an uninterpreted function that works over Q's

t1 :: IO SatResult

A satisfiable example, stating that there is an element of the domain Q such that f returns a different element. Note that this is valid only when the domain Q has at least two elements. We have:

>>> t1
Satisfiable. Model:
  x = Q!val!0 :: Q

  f :: Q -> Q
  f _ = Q!val!1

t2 :: IO SatResult

This is a variant on the first example, except we also add an axiom for the sort, stating that the domain Q has only one element. In this case the problem naturally becomes unsat. We have:

>>> t2
Unsatisfiable
