Can't definitely say anything about the logic, but at first glance, passing advanced 'nullptr' in dozen of calls looks really weird. Especially facing the fact, that the last param - in most calls named 'tExprArgs' - that means, 'our dozens of nullptrs and another boring default params we decided to move (and pass) via this tuple of arguments'.

In this struct they, at least, named. So, you don't need to enumerate dozen of 'nullptr', keeping in mind, which one means what.

Sure, this bunch of explicit pararms should be eliminated. Who knows, m.b. after it 'files changed' will reduce to couple files of code + some files of doc.
