I see, but the message "Eager macro-expansion failure" doesn't sound
like a warning to me.  Maybe use the word "warning" somewhere to avoid

The message contains no line number or any other hint where the source
of the problem is; debug-on-error is no help either.  Maybe it would be
better to get rid of the message entirely.
