Is this a front-end thing or something specific to DMD?  I'm 
wondering because I'd like something like this for GDC and LCD 
when targeting ARM microcontrollers.  The inline keyword makes 
quite a significant performance improvement in one of my current 
C++ projects, and I anticipate the same result when I convert it 
to D.

Any chance of adding a "optimize, true/false" pragma also to get 
around the lack of a volatile keyword? (Just a question, I don't 
mean to hijack this thread and turn into another volatile keyword 
debate).
