  full_sym   = "#{name}::#{sym}"
  path_parts = full_sym.split("::").map { |part|
    part.gsub! /([^A-Z])([A-Z]+)/,       "\\1_\\2" # OneTwo -> One_Two
    part.gsub! /([A-Z]+)([A-Z][^A-Z]+)/, "\\1_\\2" # ABCOne -> ABC_One

    part.downcase
  }

  require File.join(path_parts)

  # Make sure that we don't get stuck in an endless loop.  `const_get` calls
  # into `const_missing`, so we can't use that.
  eval "defined?(#{full_sym}) ? #{full_sym} : super"
