Inte riktigt, <> �r mer "magiskt" �n s�, anv�nder ev argument enligt
standard Unix filter-konvention - fr�n mansidan:

                                       Input from <> comes either
     from standard input, or from each file listed on the command
     line.   Here's how it works: the first time <> is evaluated,
     the ARGV array is checked, and if it is  null,  $ARGV[0]  is
     set to '-', which when opened gives you standard input.  The
     ARGV array is then processed as a list  of  filenames.

Varf�r inte utnyttja den beh�ndiga $_:

while (<TIDER>) {
    print;
    @pieces = split;
    ...

Absolut.
