I really like this video.. it compares doing gcd (greatest common 
divisor) in 16 different languages. If I were running a intro to 
programming course, I'd make them all watch this, as soon as they

The link below starts where he compares the C++ vs D vs Rust 
solution.

In D, you just do it and quote '.. move on'.
