Ah. The top-level lang description claims “No preprocessor”, but my definition of that word doesn’t appear to be the same as yours :/

The difference here is that a preprocessor runs before parsing and semantic analysis. In C3 compile time if runs in the analysis step, so after parsing.
So the macros and compile time execution occurs after parsing in C3, but in C everything happens at lexing, before the code is parsed.
That strategy will backfire when the grammar changes in a later release. A pre-parse step is necessary for code that targets different compiler releases.
Now I'm confused, what do you mean? What grammar changes?
