I like the different approach. But, I can not get your example to work. I get this error: 
Can't locate object method "readline" via package "IO::File"

Admittedly, I am running an older version of perl (5.8.5 on linux), but if I look at the docs for the more recent versions of perl (5.8.8 and 5.10.0) for the IO::File core module, they also do not mention a "readline" method. Does your code actually run for you? Just curious.
