literate programming in D

[nikki via Digitalmars-d-learn]

I've been googling without luck, is there a way to do literate 
programming in D?, similar to how it's done in Coffeescript ?

http://www.coffeescriptlove.com/2013/02/literate-coffeescript.html
basically me writing comments around code and some parser that 
creates styled documents from that (with highlighted source 
code), the current documentation system doesn't export the source 
code.

anybody done this before?
