Ah, yes, you are of course completely right, I guess I did too much C++ recently :)

Alternatively you could return a reference to the header, of course. But it would look kinda more ugly than the simple optional argument solution: 

my $slot = $self->header ('test');
$$slot = "New value";
print "Value for header: $$slot"; # or even $slot, if you overload the
+ stringification
