Well, it's a bit of a misfeature, IMO. Have you run a benchmark to
determine that heap allocating the right amount is substantially slower
or more complicated than keeping it on the stack? After all, this code
is only run once, so I'm a little skeptical that we gain anything in
exchange to bearing the maintenance cost of this magic value.
