Druntime was written by many people, and does not exhibit consistent best practices.

I've dealt with enough professional C .h files to conclude that #ifdef algebra 
is the worst solution. This includes the ones I have written.

The objectives of minimizing keystrokes and maximizing clarity are only rarely 
aligned.

I understand that many of D's design decisions are out of step with conventional 
wisdom. They aren't the result of reading about best practices, but instead 
decades of living with those practices.
