Defined in:

Overview

Pod: A node that can be instantiated directly with proc-based behavior. Provides an alternative to Builder style for inline node creation.

Usage patterns:

Constructor style: Pod.new(caller: ->(input, **) { input * 2 })
Factory style: External.create(caller: ->(input, **) { input * 2 })
Block style: External.create { |node| node.caller { |input, **| input * 2 } }
