Actually, NSArray implements takeValueForKey in a wacky (yet oh so 
convenient) way, so you can, belive it or not, simply do:

nsa.takeValueForKey( value, key );

Not familiar with makeObjectsPerformSelector, but from the name of the 
method, you could probably fuss around with it to make it to the same thing 
with a lot more work, but not in the way you are suggesting. That won't 
work. But takeValueForKey should do it for you.
