Sorry. I misread your earlier post.
The way that clamp blocks work is that they "push" a state, process their
contained blocks, and then "pop" the state when the next block is run. But
there isn't always guaranteed to be a next block, so I add "hidden" blocks
to ensure there is always a block to pop the stack of a clamp, A bit of a
kludge but at the time, I didn't see an easier work-around.
