So to simulate computed goto have to
1. wrap switch(x) in a loop [ while(0) ]
2. inside each case recompute x (instead of jump to computed y)
3. jump back to execute switch again [ continue ]
It does look as if a nested switch can contain case labels from
an outer switch which is very good. Did not try this out.
Any more ideas, advice?
I quess you could define a string or a template mixin to automate
this, if there are many functions doing this.
Then again, you probably should NOT have many functions working
this way -it is not at all a scalable way to program. It might be
good for something that is called very often and thus needs to be
fast, but not for regular code. Computed `goto`s are even worse
in maintainability than normal `goto`s.
