Relax, do not feel targeted. I was replying to Mats that I tend to like
more practical suggestions, like the one he commented, that are less
prone to personal taste and whose results can be measured. I didn't
attempt to implicitly suggest your proposal was silly. The _discussion_
around it is what can become silly. Do you disagree? :)

I find this one acceptable.

This is not really a burden :) We could also make a "checkpatch" bzr
hook to detect this kind of violation.

I wonder if we could measure how much space it frees.

Yeah, my point exactly.

Yeah. But, for me personally, that's almost automatic nowadays. Also, we
could automate it if we wanted to.

Yeah, but it got hijacked into a my_bool discussion...

Sure. But if you also, at the same time, propose some way to avoid
misuse, it shortens the discussion scope. For example, let's use C++
style comments but also ensure via a "checkpatch" bzr hook that it won't
be used in C files, or via -std=c89.

I think it would help and it would avoid misuse, which is what was
probably behind the said styles.
