DUB can fill this role quite well. What it needs is clearer 
documentation on how to switch compilers. Better yet, outright 
compiler switches from the command line to designate a compiler, 
compile debug code, or run unittest code.


On another note, I do want to put in my two cents about this 
controversial thread, and the continuing GC threads that pop up. 
People that use D find it highly productive and performant in 
their domains. C and C++ programmers, ostensibly the target 
audience of D, continue to reject GC as some kind of albatross 
they'll never get over.

dlang.org needs front-page, clear as day examples of the speed 
benefits of optimized D code. Show that there is minimal or no 
impact from the GC is most modern use cases (i.e. within 
components of a web framework, within a database, within a 
desktop application). Compare performance of real solutions. And, 
if it can be done, show how maximally performant embedded code 
with no GC can be run on constrained real-time hardware with a 
significant gain in code readability.

tl;dr EXAMPLES EXAMPLES EXAMPLES

SHOW the world why the GC is not only not a big deal, but a good 
thing, and STOP trying to TELL them by playing defense in 
discussion threads around the Internet.
