What do you mean? It would work fine for the purpose I've described. If 
you want to be sure you get an array when deleting multiple key-value 
pairs, use #delete_values_at, otherwise #delete is just fine. The nifty 
thing is that it adjusts its return value according to your need.

If #delete should be altered, why should #[] and #[]= ?
