I believe that is really super-good thing. As I've written elsewhere in this tracker, the most useful case for refinements is "in current module, I want some shortcuts for my code to look cleaner". For example, [here](https://github.com/zverok/drosterize) and [here](https://github.com/zverok/xkcdize) I experimented with representing some graphics algorithm in a most "readable" way, adding really small methods to core (Numeric) and RMagick objects. The point is "here, in this module, I crave for some things to exists in some objects". So, "inplace refinements" is probably the main kind of refinements the developer could care; while "refinements in a module" could be used, probably, for some "more hygienic" ActiveSupport-alike gems, or some specific blends of Ruby (like `using Geometry` with ton of specific geometry-related services added to numbers and matrices and whatnot). ---------------------------------------- Feature #16241: Shorter syntax for anonymous refinements https://bugs.ruby-lang.org/issues/16241#change-81909 * Author: palkan (Vladimir Dementyev) * Status: Open * Priority: Normal * Assignee: * Target version: ---------------------------------------- The original discussion is here https://bugs.ruby-lang.org/issues/14344. tl;dr - Refinements are often used in-place with anonymous modules - Having shorter syntax could lower the barrier of entry for Rubyist wanting to explore this feature - Previous syntax suggestions were not accepted. I suggest adding a shorter syntax (technically, API): ```ruby # before using(Module.new do refine Array do def foo;"bar";end end end) # after refining Array do def foo; "bar"; end end ``` The original idea was to use `using_refined` instead of `refining` but after discussing with Matz we decided that it's too verbose, and `refining` seems better. But is it good enough? Any thoughts? -- https://bugs.ruby-lang.org/ Unsubscribe:
