Subject: Breaking the loop in case of EOF

Hello,
I need to break a loop when program gets an EOF from STDIN.  For example
in C++ I would do it by following way:

while(1) {
  if((cin >> a).eof()) break;
}

I don't know how do it in Ruby. I tried the idea, but it doesn't work
well:
irb(main):007:0> loop do
irb(main):008:1* str = gets.chomp
irb(main):009:1> break if STDIN.eof?
irb(main):010:1> puts "String: " + str
irb(main):011:1> end
hey
joe
String: hey
hey
String: joe
hey
String: hey
=> nil

Thank you for your attention,
