I've noticed that too. ;) And I am not sure why the slicing syntax works 
because the 'printers' member is still shared then.

I had that at one point but then I could not convince myself that 
Printer.print should be a shared member function. How do we know at 
design time that every Printer would be shared? I thought that Printer 
should be as simple as possible and that shared should be handled by a 
higher-level code. Then the code became ugly like that. :)

I need more experience. :-/
