Yeah I loved working on D.  But some of the people made it very 
difficult.  So I've switched focus to other projects that use D 
rather than contributing to D itself.

Yeah they have proven to be very useful. I have many tools 
written in D and this feature allows the main source file to be a 
"self-contained" program.  The source itself is declaring the 
libraries it needs, the environment, etc. And the answer is Yes, 
all those options are supported along with a couple I recently 
added `//!debug` and `//!debugSymbols`.  I anticipate more will 
be added in the future (see 
https://github.com/marler8997/rund/blob/master/src/rund/directives.d)

To show how powerful they are, I include an example in the 
repository that can actually build DMD on the fly (assuming the 
c++ libraries are built beforehand).

/*
This wrapper can be used to compile/run dmd (with some caveats).
* You need to have the dmd repository cloned to "../../dmd" 
(relative to this file).
* You need to have built the C libraries.  You can build these 
libraries by building dmd.
Note sure why, but through trial and error I determined that this 
is the
minimum set of modules that I needed to import in order to 
successfully
include all of the symbols to compile/link dmd.

Thanks for the interest.  Feel free to post any requested 
features or issues on github.
