This is right.
It is my opinion that it is not possible to make a useful machine,
virtual or real, which executes instructions sequentially, if the
instruction set does not contain a conditional jump of some sort.
I have tried doing it using conditional calls, and it fails on
the equivalent of the first if ..., elif ... you try to write.
