Use ``-allinst``, that is a template emission bug.

Priorities may be wrong. Instead of bug fixing and stabilization, people concentrate on getting new stuff like ˋ:blubˋ into the language. It‘s interesting to see this. But it‘s not positive to watch this. The featuritis is just creating chaos, not a stable programming language you can count on.

My focus is upon making D's foundations stable, and that work comes in many forms and yes some of that is in new features which help resolve other problems in the ecosystem. Whether it be getting D's identifiers able to express recent C versions and hence interoperability, making sure how we represent and work with symbols actually work without error in common situations or just fixing random bugs where something minor was messed up some place. They are all stabilization and bug fixing tasks that I have some thing to do with. People are doing what they can to make D better, and we are all aware for those of us who actively contribute that D has a very large backlog of bugs that need resolving.
