class pyre.algebraic.Boolean.Boolean

This is a mix-in class that traps the boolean operators

The point is to redirect boolean operations among instances of subclasses of {Boolean} to methods defined in these subclasses. These methods then build and return representations of the corresponding operators and their operands.

{Boolean} expects its subclasses to define two class methods: {literal} and {operator}. The former is used to encapsulate operands that are not {Boolean} instances. The latter is used to construct the operator representations.
