All objects are passed
It follows the normal Cocoa memory management rules. The object did
not come from an alloc..., copy... or new... method, and you didn't
retain it yourself, so you do not own a reference to it. If you want
it to stick around longer than the dictionary itself, it's up to you
to either make a copy
