Feature #7836: Need a way to get Method and UnboundMethod objects to methods overridden by prepended modules

See the following code:

  module P
    def hello
      puts "from P"
      super
    end
  end

  class A
    def hello
      puts 'from A'
    end

    prepend P
  end

  A.instance_method(:hello).source_location == P.instance_method(:hello).source_location  #=> true

== Discussion

Since (({A.instance_method(:hello)})) effectively returns (({P.instance_method(:hello)})) it is impossible to get an (({UnboundMethod})) object to the original (({A#hello})) method.

Tools like ((<[Pry]|URL:http://pryrepl.org>)) need to access (({UnboundMethod})) objects to every active method in the system for debugging purposes.

== Possible solution

Simply allow (({instance_method()})) to take a second boolean parameter, indicating whether methods injected by prepended modules are to be included, it would default to true:

example:

  A.instance_method(:hello) #=> same as P#hello
  A.instance_method(:hello, false) #=> return strictly A#hello
