Kill toRenderedDocumentMarker() by using tighter typing. This method was doing no type validation, just a static_cast<>().

Believe it or not, we don’t even need the local variable here. This will work:

    for (auto* marker : markersFor(node)) {

However, some other similar constructions wouldn’t work. Only the result of the entire expression on the right gets its lifetime extended in the right way. So maybe you don’t want to do this?

Same thing again.

Same thing again. Also not sure why we bother putting the const here; doesn’t add much.

A line like this is where other people hate, and I love, auto.

Could use a modern for loop here.

Seems like these should all take references, not pointers.
