Huh, that's interesting.  As someone who spent years maintaining a
huge multi-process application written in assembly language -- where
jump tables (dispatch arrays, essentially) are The Rule -- I find case
statements much easier to read in most (not all) situations.

I think that means we may not reach a consensus on readability for
some such things.
