Feature #5005: Provide convenient access to original methods
https://bugs.ruby-lang.org/issues/5005#change-34662

Author: lazaridis.com (Lazaridis Ilias)

Target version: next minor


The languag allows a class to be "reopened", thus it's behaviour can be redefined:

class String
  def any_method
    #custom code
  end
end

the original method can be called, using this construct:

class String
  alias_method :original_any_method, :any_method
  def any_method(*args)
    #custom code
    original_any_method(*args)
    #custom code
  end
end

In order to make this more convenient, the following construct could be provided:

class String
  def any_method(*args)
    #custom code
    original # call the original String#any_method, passing *args (similar to "super")
    #custom code
  end
end

 "original" would behave similar to "super"

The term "original" can be replaced by any term which describes this concept better.
