And start to debug the cpp output if anything goes wrong, I may add.

Not including headers from other headers as a rule leaves at least a slight
chance of understanding for those unfamiliar with a program's structure.
Source files stay somewhat self-contained, and you can see what's imported
without following each and every header three levels deep.
