Can you share feature(s) in D people are not talking about which you've found very useful?

In my experience, using appropriate attributes for functions, variables, etc... doesn't happen like it should. This includes attributes like `@safe`, `immutable`, `pure`, `const`, and others.

I recently watched of video where Andrei acknowledged this when talking about the `pure` attribute (https://youtu.be/WsgW4HJXEAg?t=3052). It was also acknowledged somewhat by Walter in his talk at DConf 2017 (https://youtu.be/iDFhvCkCLb4?t=2531). As I understand it, though, the D compiler has some logic to automatically infer some of these attributes, but because its *invisible* to the user it's difficult to predict what those inferences are, and there's no documentation that I'm aware of that defines how/where/where this happens.

IMO, part of the problem is that D has the wrong defaults (e.g. `immutable` by default, `@safe` by default, `final` by default, etc...), so users have to opt in to these things when they should really only be opting out of them. Unfortunately, changing this would be disruptive and will probably never happen without a fork.
