Hi Yusuke, I guessed it was a joke, but I couldn't get it at that time. Actually I had a hard time reading "CONCAT" in your last example. After that, I could read it too in the first ones, which is much harder :) I guess I have some problem with my brain! :D ---------------------------------------- Feature #6265: Remove 'useless' 'concatenation' syntax https://bugs.ruby-lang.org/issues/6265#change-25749 Author: rosenfeld (Rodrigo Rosenfeld Rosas) Status: Assigned Priority: Normal Assignee: mame (Yusuke Endoh) Category: Target version: 3.0 What is wrong with this code: some_method 'argument1', 'argument2' 'argument3' Yes, the missing colon, but it is not always easy to notice that... What is this ('concatenation' 'syntax') useful for? Why writing ('some ' 'concatenation') instead of 'some concatenation'? A missing colon between string arguments can lead to some bugs that may be hard to find, specially if the arguments are optional. And I can't see any useful case where this allowed syntax for concatenation would help. -- http://bugs.ruby-lang.org/
