Overview

Does not tolerate duplicate keys by default. Override ‘key_collision` to change this.

Example:

DTC::Utils::Visitor::DSL::accept(DTC::Utils::Visitor::HashBuilder) {
  container(:arg1) { child_item(:arg2) }
  root_child_item
}.root

=>

{:container=>{nil=>[:arg1], :child_item=>[:arg2]}, :root_child_item=>[]}
