> This is another missing optimization.
> We often have parsers that have nested <seq>....</seq>
> This is never needed as these can be merged. This improves tracing and debugging by avoiding having these excess things there.
> It also simply reduces the number of parser 'actions' a bit, so can't hurt for performance reasons. Every parsed element seems to have at least one excess <seq>...</seq> created around it.
