Hello. `IO.new()` IO.new() wants a number. ~~~ruby io = IO.new(1) ~~~ Would it be possible or desirable to also allow symbols? Such as: ~~~ruby io = IO.new(:stdout) ~~~~ The `:stdout` :stdout seems to make it slightly easier for me to remember which of the variants (0,1,2) is which (`stdin`, `stdout`, `stderr`). (stdin, stdout, stderr).
