Compare with:

deprecate(*method_names)

deprecate :foo

deprecate bar: 'message'
deprecate :foo, :bar, baz: 'warning!', qux: 'gone!'

You can also use custom deprecator instance:

deprecate :foo, deprecator: MyLib::Deprecator.new
deprecate :foo, bar: "warning!", deprecator: MyLib::Deprecator.new

Custom deprecators must respond to deprecation_warning(deprecated_method_name, message, caller_backtrace) method where you can implement your custom warning behavior.

class MyLib::Deprecator
  def deprecation_warning(deprecated_method_name, message, caller_backtrace = nil)
     message = "#{deprecated_method_name} is deprecated and will be removed from MyLibrary | #{message}"
     Kernel.warn message
  end
end
