Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Replace a whole compound boolean with nil: a && b becomes nil, and the same for || and the and / or keyword forms.

Where BooleanOperandPromotion drops one side, this drops both. The survivor it targets is a condition whose value is never asserted — code that runs the expression for its side effects, or a test that only checks the branch was taken rather than what the branch was given.
