We have a little problem. TokenAnnotator::resetTokenMetadata() resets the type, except for a (growing) whitelist. This is because the TokenAnnotator visits some tokens multiple times. E.g. trying to identify if a < is an operator less or a template opener. And in some runs, which are bascially "reverted" the types are reset.

On the other hand, if the parser does already know the type, it should be able to set it, without it being reset. So we introduce the ability to set a type and make that final.
