module Dry::Initializer::Plugins
  # Plugin builds a chunk of code for the initializer's signature:
  #
  # @example
  #   Signature.call(:user)
  #   # => "user"
  #
  #   Signature.call(:user, default: -> { nil })
  #   # => "user = Dry::Initializer::UNDEFINED"
  #
  #   Signature.call(:user, option: true)
  #   # => "**__options__"
  #
