I have no idea what the possible purpose of redefining String#to_s is.
However, I think this brings to mind an interesting idea. As part of
Ruby's duck typing initiative, many methods call to_str on objects
they expect to be strings. Having String#to_str return something other
than self could produce some extremely confusing results.
