Refinements: allow modules inclusion, in which the module can call internal methods which it defines.
Right now this isn't possible:
module Extensions def vegetables ; potatoe ; end def potatoe ; "potatoe" ; end end module Refinary refine String do # this doesn't work include Extensions # this would work... # def vegetables ; potatoe ; end # def potatoe ; "potatoe" ; end end end using Refinary puts "tomatoe".vegetables #=> in <main>': undefined method 'vegetables' for "tomatoe":String
Wrongly reported as a bug here.
According to Shugo Maeda, this was expected behaviour. I argued that this is the way most monkey-patches work, and if Refinements can't cover the use case of inserting a custom DSL which references itself in the classes it refines, it can't fully replace monkey-patches, which I read was the main reason Refinements have been added to the language.
