Bug #16790: string format and refinements
https://bugs.ruby-lang.org/issues/16790

* Author: dsisnero (Dominic Sisneros)
* Status: Open
* Priority: Normal
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN
----------------------------------------
require 'pathname'
module PathRefinement

  refine Pathname do

    def to_s
     '"%s"' % self 
    end
  end

end


module Builder

  using PathRefinement


  def call(s,params)
    cmd = s % params
    puts cmd
    system(cmd)
  end

  module_function :call
end

file = Pathname($0).expand_path

Builder.call("cat %s", file)

-------------------

C:\Users\Dominic E Sisneros\source\repos\ruby\refine_pathname>ruby system_refinement.rb
cat C:/Users/Dominic E Sisneros/source/repos/ruby/refine_pathname/system_refinement.rb
cat: 'C:/Users/Dominic': No such file or directory
cat: E: No such file or directory
cat: Sisneros/source/repos/ruby/refine_pathname/system_refinement.rb: No such file or directory

expected 

cat \"C:/Users/Dominic E Sisneros/source/repos/ruby/refine_pathname/system_refinement.rb\"

because format %s is supposed to call to_s
