Ah, I see. I misunderstood from your example above.

I do agree that automatically stamping with __FILE__ and __LINE__ is
very helpful there. Could we maybe restrict that use of the variadic
macros to a few known-good compilers (maybe #ifdef __GNUC__, which also
hits clang, and something to catch MSVC)? On other systems it would
become a compile-time noop, and they could live without the feature.
