Instead of putting "Foo" as type into the list macro, and then extending to "type*" at consumer macros, put "Foo*" into the macro. This is in preparation for incremental transition to ObjectPtr, where some roots will return pointer types and others won't. When that migration is complete, everything will be uniform (and without "*") again.
