I get that this is unable to create dysfunction other than "doesn't build".

My issue is that a silent language change with no changelog entry and no spec
change. This issue is exactly similar with introduction of named arguments.

Perhaps yes the language is better afterwards; but since there is no way to
know, there is no knowledge one has to test things that worked for a long time
under compilers that are a few versions back.

If this happen like this, then Editions when compiled with new compilers, won't
work in old compilers, somewhat bypassing the advantage of Editions.

I develop libraries with users and we do not have the same compilers, so users
expect me to test with multiple compilers yes but it is helpful to have a way
to track breaking changes or additions like these in changelog. And it's not
sure if intentional here.
