Also, keep in mind, depending on the lang of course, throwing exceptions 
is not generally a fast thing to do.  Exceptions should be used (IMO) 
for "exceptional" situations, where something does not behave as it 
should.  A cache key miss is an entirely valid outcome from a cache 
request.  Not an exception in my mind.

Does PHP not have nulls?
