On the other hand they have gained appreciation in almost every 
one of the other recent languages, as F#, Scala, Rust, and few 
Java-Like languages running on the JavaVM, so this is a not small 
failure point of D. I think all type-rich languages that will be 
designed in future will have nonnullable typing. D is  old-school 
on this.
