one but they refused[1] (doesn't behave exactly as C#'s
actually), Kotlin also got something in this area[2]
What some D ways to avoid those checks?

Hi Jack,
I have created this example implementation of the "Null safety"
pattern using templates in D:
https://github.com/ddcovery/d_null_safety
It is, basically, a monad (functional programming orientation)
with some syntax sugar taking advantage of the power of templates
in D.
