I think this is worth exploring.
- It already exists in C, so not re-inventing anything, and minimizing learning cost
- This would potentially provide performance benefits as parser can skip it altogether without AST or subsequent string initialization.
- In the long run could adopt multi-line comment standard. E.g. markdown or rst, so that IDEs can apply appropriate syntax highlighting for inner code and patterns.
Strong +1 for testing the waters for this again.
