Sorry I didn't know this. I have never seen ++ in ruby code (except probably in books) and that made me think it is not valid syntax. Wonder what is the usefulness of '1 + +1' though. ---------------------------------------- Feature #6222: Use ++ to connect statements https://bugs.ruby-lang.org/issues/6222#change-25389 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/
