Hello.

`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` seems to make it slightly easier for me 
to remember which of the variants (0,1,2) is which
(`stdin`, `stdout`, `stderr`).
