I like the idea behind it. I am not sure about the syntax itself. Would this break existing code? What are the constraints how it is used? ---------------------------------------- Feature #12578: Instance Variables Assigned In parameters ( ala Crystal? ) https://bugs.ruby-lang.org/issues/12578#change-59578 * Author: Matt Lankford * Status: Open * Priority: Normal * Assignee: ---------------------------------------- When I first saw the instance assignments in Crystal, I was floored... I have looked at all 18 pages in this tracker and thought it "must" have been mentioned in here... but I don't see it... pardon me if I missed it... BUT so in Crystal, this : ```ruby class MyStuff def initialize @thing_one , @thing_two end end ``` would replace : ```ruby class MyStuff def initialize thing_one , thing_two @thing_one = thing_one @thing_two = thing_two end end ``` One of the things I loved about ruby was `attr_accessor` / `reader` / `writer`... I know in Crystal, it is a macro, but still at the millions of lines of boilerplate that would go away... Has no one thought of stealing this from Crystal or is there a good reason this does not exist? ( and I will go sit down and color now ) -- https://bugs.ruby-lang.org/ Unsubscribe:
