Interestingly, I've been seeing that what makes D code much more robust is a consequence of 'unittest' coupled with -cov.
It is big deal breaker for personal projects and open-source collaboration. For big private projects agreeing on single testing framework and adding one of coverage analyzers to the CI is not that much of a problem. Convenient, but not a deal breaker over C++.
But being less afraid to actually write code because of more powerful type system and safer defaults - this is huge.
I think most important thing about built-in unittests is how this feature encourages to add tests when contributing to projects that don't currently have any real coverage. It becomes so easy that there is not reason to not do it and this help open-source a lot.
