Overview

A value object represnting the .loom file pattern declarations. The difference between a Loom::Pattern::Pattern and Loom::Pattern::Reference is a pattern has no association to the context it should run in. It is simply a value object with pointers to its assigned values from the .loom file. However, a Reference includes it’s DefinitionContext, including nested before/after/with_facts/let hooks.
