I surely saw it when I inspected the session API, but was appalled by the
low-level nature. After having fumbled for an hour or two, I can confirm that
initial impression ;).  At least I know that once I am done nobody will question
my indispensability..
 
My currently remaining problem is: how do I obtain a key from an object?
