If the variable's name is nil, all kinds of things stop working

Can you give an example? Are you trying to use nil as a variable name in Arc, or simply to have a data structure representing variables where some of those variables are named nil?

I'm creating a compiler for a class, and I've been representing variable names in the ast with symbols. I could use strings instead, and may end up doing so, but symbols seemed a more elegant solution.
