Yusuke, am I supposed to understand what you meant with the code in your last comment? If so, I didn't get it... Nikolai, good point, I haven't thought about this before and I wasn't wondering :) But do you really think that this could have some meaningful impact in the performance of replacing '\' with '+'? ---------------------------------------- Feature #6265: Remove 'useless' 'concatenation' syntax https://bugs.ruby-lang.org/issues/6265#change-25698 Author: rosenfeld (Rodrigo Rosenfeld Rosas) Status: Assigned Priority: Normal Assignee: matz (Yukihiro Matsumoto) 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/
