I wasn't clear. Your Perl problem arises because there is more than one
false value for strings: "", "0", "0.0" and you must keep them all in
mind while working with strings. That's not the case for Python. And of
course it is also not a problem for Ruby either.

What happens in end-of-file for Ruby? Can a read() value return failure
in multiple ways or just one?
