    #  class MyCallableObject < LunaPark::Extensions::Callable
    #    def initialize(params)
    #      @params = params
    #    end

    #      'call used'

    #    def call!
    #      # do some stuff with @params
    #      'call! used'
    #    end
    #  end

    #  MyCallableObject.call(params)  # => 'call used'
    #  MyCallableObject.call!(params) # => 'call! used'
