Sometimes I see runtime facilities used as compile time and I'm 
having a hard time distinguishing that. It is even possible to 
use it with meta-programming facilities.

It is a powerful feature that can help to improve the 
expressiveness and efficiency of D programs, but it can also make 
code more difficult to understand and maintain.

Do you have a solid recommendation about distinguishing?
