--- Comment #10 from Eyal <e...@weka.io> --- I think a new "transition" compiler flag [1] can be added to warn about the changes in behavior here. It is possible to make these warnings the default for a few versions (with a flag to suppress them), but I think code relying on this bug for correctness is probably very rare. One can always opt-in to all transition warnings via -transition=all when upgrading the compiler. This seems in line with how D warns about other language changes.
