Call original method when monkey patching

Ruby offers monkey patching methods in order to change the behavior of a library if there's no better way.

We can call the method we're overriding inside our monkey patch:

class Foo
  def bar(argument)
    'Hello' + argument

module FooExtensions
  def bar
    super(' in my') + ' World'

class Foo
  prepend FooExtensions # the only change to above: prepend instead of include
end # => 'Hello in my World'

As mentioned, monkey patches are usually a threat to your code quality, so try to avoid them if possible.
