D embraces something called design by introspection - that basically means adapting behaviour at compile time based on what a parameter can do rather than what a parameter should do (in the case of a template). This allows you to write extremely expressive (and fast) code, however you do at this point need to test at a more granular level. https://www.youtube.com/watch?v=HdzwvY8Mo-w https://www.youtube.com/watch?v=HdzwvY8Mo-w
