Hi, I realize that the lvalue syntax looks a little weird, maybe I should kick it out and just have: 
$obj->header('test'); # Get header 'test'
$obj->header('test','new value'); # set header test
$obj->header;         # Get all headers as hash

You C++-ish suggestion: 
my $hdr_slot = $self->header ('test');
$hdr_slot = "new value"; # Set
print "New header: $hdr_slot\n"; # Get

doesn't work in Perl because there all objects are references (to talk C++: from type *myclass not myclass). So assigning to $hdr_slot would make this variable a string with the value "new value" and would remove the reference to the object. Overloading the '=' operator only is used for generating temp copies for operators like '+=', so far I know.

The only way to do this is to tie a class to $hdr_slot. Then you can define a STORE method which gets called at every '='. See 'perldoc perltie' for more.

I read all this in the book 'Object Oriented Perl' just two weeks ago.
