> A top-level unittest that is not marked with @betterC in Phobos causes no
> trouble in betterC mode. However, inside a template that's not the case:

@betterC is not a language / compiler feature. It's an "user" (druntime/phobos)
defined annotation used by the test_extractor to mark unittests that should be
tested in a generated module compiled with -betterC.
