Status changed from Open to Assigned Assignee set to matz (Yukihiro Matsumoto) Hello, I would be even happier if you respond that ticket instead of adding a new one... Of course, '++' also causes compatibility issue :-) p 1 ++ 1 #=> 2 '++' may be confusing because it is used for string/list concatenate operation in some languages, such as Haskell and Erlang. It looks a method to me. -- Yusuke Endoh ---------------------------------------- Feature #6222: Use ++ to connect statements https://bugs.ruby-lang.org/issues/6222#change-25378 Author: gcao (Guoliang Cao) Status: Assigned Priority: Normal Assignee: matz (Yukihiro Matsumoto) Category: core Target version: I propose to use ++ to connect two or multiple statements, e.g. do_this ++ do_that ++ do_something It is equivalent to (do_this; do_that; do_something) but more readable. It can be used to replace below idiom do_something and return if condition with do_something ++ return if condition The current way is very error prone because do_something might return false/nil in some cases and cause problems. And new Ruby programmers might not understand the meaning behind this idiom and mimic it blindly. I noticed someone proposed 'then' for same purpose (See http://bugs.ruby-lang.org/issues/6201) but is postponed to 3.0 because it is already a keyword. I like 'then' too but if it is not acceptable due to backward compatibility issue, then '++' is a good alternative. -- http://bugs.ruby-lang.org/
