I just want to mention that, actually, IWYU doesn't probably need any resugarer at all. A type template argument as-written is needed just to decide whether its canonical type should be reported for `#include`ing or not (e.g. because the `typedef` author has provided it already). Another way to do it is to collect a list of types blocked for reporting before scanning the instantiated template. I started rewriting IWYU in that direction some time ago.
