That would work too, although I think it might be a bit harder to use
than one alternating-name-and-value array, at least in some scenarios.
You'd have to be careful that you got the values in the same order in
both arrays, which'd be easy to botch.
There might be other use-cases where two separate arrays are easier
to use, but I'm not seeing one offhand.
