The function's switch may well be translated into a table,
so memory consumption may be the same, albeit in a different
section of the executable. It might be even more then, since
the packing does not occur. If so, it may be possible to
prevent this by using IF.

Like the translation of the switch, speed of lookup
requires experimentation, I think, that's usually been
the only reliable predictor given an implementation.
