Synopsis
information operators: least upper bound (lub) and greatest lower bound (glb)
Description

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.
