in reply to Open pipe to a function?

If you are going to pipe it to a script, then I believe it has to be in another script.

If all you need to do is write STDERR to a file, why not just do this at the beginning of your script: 
open(STDERR, '>error.txt');

Update:Try using IO::Tee, like suggested by Roy Johnson. I included a sample in my reply to you below.

    I can't just redirect it, because I also want to see it at runtime.

      You could probably do some tricks with IO::Multiplex. Just save the orginal filehandle like this:

      my $old_stderr = *STDERR;

      And then reopen STDERR with IO::Multiplex with $old_stderr and a filehandle to the log file.

      How about 
      use IO::Tee;
open(ERRLOG, '>error.txt');
my $tee = new IO::Tee(\*STDOUT, \*ERRLOG);
*STDERR = $tee;
