2205: Implement bulitin line! macro r=matklad a=edwin0cheng This PR implements bulitin macro `line!` and add basic infra-structure for other bulitin macros: 1. Extend `MacroDefId` to support builtin macros 2. Add a `quote!` macro for simple quasi quoting. Note that for support others builtin macros, eager macro expansion have to be supported first, this PR not try to handle it. :) Co-authored-by: Edwin Cheng <edwin0cheng@gmail.com> |
