lub: information operators: least upper bound (lub) and greatest lower bound (glb)
Lub is an experiment in computing least upper information bounds on
(partially defined) functional values. It provides a lub function
that is consistent with the unamb operator but has a more liberal
precondition. Where unamb requires its arguments to equal when
neither is bottom, lub is able to synthesize a value from the
partial information contained in both of its arguments.
This module also defines glb, which intersects information.
