CLtL is vague about the order of evaluation of function arguments.
Actually, CLtL pg 61 says that the arguments and parameters are
processed in order, from left to right. I don't know if "processed"
implies "evaluated", but I always assumed (perhaps incorrectly) it did.
"Arguments" are the output from evaluation, not the input to evaluation.
Think about the case where the function was called by APPLY.
