I start to grow fond of msl, I will still stick with my hlsl variant but may change the annotation style to C++11 attribute syntax. I already use that for all customs things for my graphics api/ shader lang already.

Got debugging a windows app (wine) on MacOS working now as well, this really cool!

Cross compiling to windows... check
Running windows exe via wine... check
Debugging via wine dbg... sadly can't get it to work :(
But its pretty cool to develop for Windows on my Macbook!

Actually you don't need xcode. #gamedev
(Added running/debugging applications directly on the simulator to my build system.)
