Exactly. D is a lot more flexible, but looking just at
MyCoolRange, you cannot actually see it conforms to InputRange
without looking at the unittests (or wherever else the static
assert is inserted).

I haven't actually tried to recreate the stuff that Rust does with
types in D. I expect some of it is possible, but the addition is
things like Unique (which I haven't tried). And this escalates.
You end up with `Unique!(NonNull!(MyClass))` and probably even
more type decorators.

If I'm not mistaken, people of the D community have tried to
market the language quite heavily. I don't know why more people
haven't joined, and it's even more baffeling to see the comments
on Reddit calling D related posts spam and speaking negatively of
the marketing on a site where upvotes dictates the ranking on the
front page.
