I think it should return ''something'', though I'm unsure as to what. For example, in the memcached libraries we call, add() returns True or False depending on whether the key gets added or not.

One of the reasons behind this is so that locking can be emulated through the cache with a single add() call. Currently you'd have to add() some unique value, then get() it back out and compare the values."		closed	Core (Cache system)	dev		fixed	cache add		Design decision needed	1	0	0	0	0	0
