Description

I just wanted to extract characters at certain indices from a string and noticed that there's no values_at counterpart for String.

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, e.g.:

string = 'hello, world!'
string.chars_at(0, 5, 7, 12)  #=> "h,w!" 
string.chars_at(0..4, 7..11)  #=> "helloworld"
