This example: [comment.7z](/uploads/7ff4fd6e90ee814b5ed9c87140154bb2/comment.7z) demonstrates two things related to `//` comments. (Actually one thing, which I propose to split in two.) First is that such a comment breaks out from `{$include}` that does not end in a newline. Second is that macro ending in a `//` comments out the rest of the line, allowing for some interesting debug constructs. **FR**: end `//` when include ends, but preserve its behaviour in macros.
