To expand on that: I had to do so because this particular std::list isn't part of any external API of the libraries in question, it's not passed around or returned, it's purely an internal implementation detail. Our wiki page makes it sound as if only using the problematic types in the external API is an issue. That is not the case, it's already just _using_ these types that's problematic.
