class Parslet::Atoms::Entity

This wraps pieces of parslet definition and gives them a name. The wrapped piece is lazily evaluated and cached. This has two purposes:

Avoid infinite recursion during evaluation of the definition
Be able to print things by their name, not by their sometimes complicated content.

You don’t normally use this directly, instead you should generated it by using the structuring method Parslet.rule.
