Standardizing existing practice is certainly an acceptable way for WG21
to operate. The paper shows the existing practice and the ODR trap,
as well as a broad array of real-world examples.

Is "integer literal" what you want to say here (it might contain
digit separators, which is unhelpful)?
Maybe "/decimal-literal/ consisting exclusively of /digit/s?"
(In former times, one could say "comprising", but that word is
tainted these days.)

I agree that an error is preferable over wrap-around.

Otherwise, ship it.

(EWG might still think a new preprocessor facility isn't worth having,
but you can't find out until they have a paper in front of them.)
