i have a feeling you're asking the wrong question. what is the purpose of
this behavior? how would your program know there is no more data? you
could just store your data in a variable and print when you're ready. you
could also tie the filehandle. you might also take a look at
Output::Buffer. it looks like that one uses Tie::Filehandle::Buffer so
you'd be using tie in the end that way.
