Examples: Why is implementation code in header files?

FWIW thinking about how our SOUL codebase has ended up being structured (which is a good example at about 15 KLoC of extremely gnarly logic), a rough overview is: the nature of writing a compiler means you have a lot of classes, mostly small. And almost all the small classes (certainly anything under about 200LoC) are inline many bigger classes that are only used by a single piece of client code (i.e. are only included in a single .cpp file) are inline classes that are widely used across the w…
