D source code formatter

[psychoticRabbit]

I rely (heavily) on clang-format in my C code. It save me so much 
effort and has become a vital day to day tool for me.

I was wondering whether D also has a 'reliable' source code 
formatter.
(reliable being a key word there).

Also, if it does, then why is it not included in the distribution 
- given the importance of consistent source code formatting these 
days.
