Is there any other language that does any of this? I don't think 
any language does all of it, so do you plan to wait a couple 
decades for any language to do it before you start programming?

Some of these are worthwile suggestions, but nobody's doing them 
yet. I suggest you start implementing them somewhere- maybe here, 
dub is an OSS project: https://github.com/dlang/dub - rather than 
lecturing others about how it's all so obvious. That way, you can 
actually get some work done before the cows come home. ;)
