But in Crystal he also uses classes and doesn't mark methods as final. 
And it's faster than D.

This is not to start a war, maybe one day I'll have to use D in my 
workplace so it better be nice and fast (so it's better if all tools are 
good).

At least in this case, the compiler should detect that the class isn't 
inherited and that you are creating an executable out of the program, so 
it's can't be a library, and mark the methods as final. And with escape 
analysis (something that Crystal also lacks, but other languages have) 
the compiler could figure out that the class doesn't need to be 
allocated on the heap.

In short, I think we need smarter compiler, not more keywords to 
optimize our code.
