Looks sane, but where did you actually find cases of this in real life?
I think we have one computed goto in the kernel, that does an array
label load. They are very rare, and when they are used, that tends to
be the normal pattern.
Just about the only place I've ever seen them are in that kind of
interpreter loops for instruction dispatch tables.
