That does make sense - since it doesn't do anything in terms of allocating memory for it and the like.

I was mainly thinking in case they later wanted to know that there were 15 instances of X, 12 instances of Y, and 2 instances of Z, then the code would have that...

But since they didn't say anything about wanting that, I suppose it would make more sense to do the undef instead and then later easily add in addition functionality like counting.
