Uhm... are you SURE this is actually nicer on your SSD?  For 
all you know, it could be writing the 806KB first and then 
optimizing that in-place to reduce it to 18KB...  Just because 
the final file size is small doesn't mean there aren't any 
large intermediate files.

no. there are no intermediary files. just this, and only this:

(bytes)
145 EZ_Compiler_tmpfile.d
15,360 EZ_Compiler_tmpfile.exe
18,384 EZ_Compiler_tmpfile.obj

On Linux dmd can do `-defaultlib=libphobos2.so` for the same

yes. but why?

 - is it technically too difficult? (ldc seems to have overcome 
that, if that's true)
