No, the homework I've seen our students do is _much_ more difficult. ;-)

I just noticed that:
print join ", ", @list, "\n";
produces output such as:
a,
a, b, c,
whereas:
print join(", ", @list), "\n";
produces:
a
a, b, c
(no trailing comma) -- strange... I think I remember reading somewhere that
without the parentheses 'join' doesn't really know exactly where to stop.
Sound right?
