    I think we used to have on build bot using it.

    I noticed because I find it useful and have it enabled locally. So I
    agree, it would be nice have cmake enable it by default :-)


It has been discussed several times. The warning has a very non-trivial compile time overhead, so it made sense to enable it on a couple of bots rather than by default.

I couldn't find a PR?

If a non-analysis feature is slow enough that we can't use it ourselves it then it's not ready to ship -- could you file a PR with the details you remember and links to any discussions?

The comment lexer/parser/sema is very heavy right now but I suspect we can get a lot of mileage out of a highly simplified alternative scheme that'd be sufficient to support -Wcomments and refactoring.

CC'ing in Dmitri so we can get a handle on this. I'd like to help
