Subject: Re: Print method

So initially I said that Thiago Massa's class String extension worked, 
and it does to a point.  But not for numbers, at least not without 
further mods.

class String
  def print
    puts self
  end
end

"abcd".print  # This works

1.print  # This causes a Fixnum error

because "print/puts expects a string,and it will call to_s automatically 
on the argument if it is not."

What's nice about this is that it's automatic.  No need to convert a non 
display number to display type in order to print it. Saves a lot of 
work.

and then there's this:
"Hello world!".display  # This works fine!
