Thanks, Dennis! I realized that there's a keyword for it, and here are the unresolved betterC-tagged issues:

https://issues.dlang.org/buglist.cgi?bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&keywords=betterC&keywords_type=allwords&list_id=243519&query_format=advanced

23468 wasn't tagged properly so I fixed it.

Thank you. I added a bugzilla for it:

https://issues.dlang.org/show_bug.cgi?id=23606

In the future, I'd appreciate adding bugs to bugzilla, then linking to the issue in any n.g. discussion of it.

This is handy on embedded. Great work, Walter! :)
