[ruby-core:110228] [Ruby master Feature#14022] String#surround

[schmijos (Josua Schmid)]

Issue #14022 has been updated by schmijos (Josua Schmid).


I've got another example of how I'd like to use `surround` in Rails string building:

```rb
model_instance.name.presence&.surround('(%s)')
# or
model_instance.name.presence&.surround('(', ')')
```

----------------------------------------
Feature #14022: String#surround
https://bugs.ruby-lang.org/issues/14022#change-99512

* Author: sawa (Tsuyoshi Sawada)
* Status: Rejected
* Priority: Normal
----------------------------------------
After joining the elements of an array into a string using `Array#join`, I frequently need to put substrings before and after the string. 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>"
```
