Smart people use hash slices. Really smart people use 'undef'd hash slices to save memory.

undef'd hash slices save time not memory.

Update: Also, as pointed out to me in a previous post, only use this method if you don't care about the values of the hash, as the values do not necessarily get set to undef.
