Instantize

Instantize converts module methods into instance methods such that the first parameter is passed self at the instance level. This promotes DRY programming when wishing to offer both an inheritable and a module callable procedure.

  module MyModule
    extend Instantize

    def self.jumble( obj, arg )
      obj + arg
    end
  end

  class String
    include MyModule
  end

  MyModule.jumble( "Try", "Me" )  #=> "TryMe"

  "Try".jumble( "Me" )            #=> 'TryMe'

Notes

This module used to be called PromoteSelf. Instantize is more descriptive, but a better name is probably still out there.
