I was able to write some D last week!

I am bumping the arsd repo dub's version number to 4.0.0. (this 
is super super arbitrary for me though, I very rarely ACTUALLY 
break backward compatibility, in fact I try to be both backward 
and forward compatible with myself and with dmd versions, just 
meh)

Anyway, while version numbers are silly, you can read a more 
informational summary of a bunch of the new stuff here:
