The central problem is not the goto, but the label it jumps to. When you=20
see a goto, you can look for the label until you found it.

When you see a label, you can look for goto's that jump there, but you=20
can never be sure that you found them all.

To reason abour the state your SW is in after the label, you must have=20
found all the goto's that jump there, and then mentally merge the states.
