I should have mentioned: I tried that in the morning ;)

Well, I did not introduce any executeVoid, because generally everything is an expression with a return value.
But I tried to rewrite the SequenceNode based on what I saw in your Ruby implementation. Also, because my pervious not so good experience with @ExplodeLoop. But, the effect was zero.
Normally, the PE should see that `last` is never read but at the end.

Is the executeVoid an essential thing? Did you notice any difference with having it/not having it?

Thanks
Stefan
