For newcomers doing the jump from C++ to D and current D users,
wanting to program on windows, the missing windows import files
are like a major step back. In C++ you got the full headers &
stuff - ready to use.
The incomplete 'core.sys.windows.windows' isn't enough and
sometime interferes with the necessary definitions you do on your
own since you are forced to do it.
This way to exclude most windows users and thats where you might
win a lot of new programmers, due to the nice support via Visual
D.
Is that on the agenda/road map?
