It does not matter that much if it is macro or mixin. Key feature 
is AST reflection which allows to augment valid D code with 
additional semantics when appropriate. It is very similar to how 
UDA's augment declarative approach, but applied to 
imperative/procedural instead. We can't do that in D right now. 
Only way is to import own source file and parse it which does not 
really sound sane.
