Subject: Re: trap(:INT); system(); STDIN.gets(); ^C

Might be worth to mention that both of the alternatives below will 
immediately exit after ^C


### ALT 1
trap :INT do
  puts
  puts 'Bye'
  exit
end

puts IO.popen('date').gets
print 'Say something: '
STDOUT.flush
puts "You said: #{STDIN.gets}"


### ALT 2
begin
  system 'date'
  print 'Say something: '
  STDOUT.flush
  puts "You said: #{STDIN.gets}"
rescue Interrupt
  puts
  puts 'Bye'
  exit
end
