Overview

A wrapper for conditional logic that can be evaluated against an object. This class encapsulates different types of conditions (booleans, symbols, callables, arrays) and provides a unified interface for checking if a condition is satisfied by a given object. It handles negation and ensures proper context when evaluating conditions.
