Description

A mutation rule for mutually exclusive mixins.

If active, such rule will cause a mutation that adds one of the mutually exclusive mixins, to remove all others.

For example, if a, b, and c are mutually exclusive mixins, any mutation that adds, say a, to an object, will automatically remove b and c from it.
