I'd therefore like to propose two new `String` methods: * `chars_at(selector, ...) ��� new_str` * `bytes_at(selector, ...) ��� new_str` which work basically like [`Array#values_at`](http://ruby-doc.org/core/Array.html#method-i-values_at), e.g.: ```ruby string = 'hello, world!' string.chars_at(0, 5, 7, 12) #=> "h,w!" string.chars_at(0..4, 7..11) #=> "helloworld" ``` -- https://bugs.ruby-lang.org/ Unsubscribe:
