From: matz@... Date: 2017-12-12T14:12:41+00:00 Subject: [ruby-core:84218] [Ruby trunk Feature#14022] String#surround Issue #14022 has been updated by matz (Yukihiro Matsumoto). I see `ary.join.surround("<",">")` to be no better than `"<#{ary.join}>"` or `"<"+ary.join+">"`. If the wrapped expression is long, you can `format("<%s>", long_expression)`. I am not sure why you are so eager to chain method calls here. Note: I am not rejecting the proposal (yet).

In such case, I would have to use either of the following: ```ruby [1, 2, 3].join(", ").prepend("<").concat(">") # => "<1, 2, 3>" "<#{[1, 2, 3].join(", ")}>" # => "<1, 2, 3>" "<" + [1, 2, 3].join(", ") + ">" # => "<1, 2, 3>" ``` but none of them is concise enough. I wish there were `String#surround` that works like this: ```ruby [1, 2, 3].join(", ").surround("<", ">") # => "<1, 2, 3>" ``` -- https://bugs.ruby-lang.org/ Unsubscribe:
