We had a similar discussion already. This involves some kind of re-evaluation of some of the input sequence after changing the internal state of the preprocessor. Wave currently does not support this.
Is it hard to make wave support this? I was thinking that with some guarantees from wave, wrt side-effects in the context, it could be really useful. The guarantees that I think would be needed are rollback-semantics in face of exceptions and no side-effects *before* callbacks are called. This would allow for backup of the context only if needed. Depending on how much work would be necessary I could work on it too for my SoC proposal, since it would easy a lot my work on the features I would implement.
