A few questions

[Namespace]

Therefore i hope that it will be official added into D.
Otherwise of course i use it only for projects between me and my 
other students.

I don't know what is wrong with this shorthand. So why don't give 
it a try?
I'm absolutely sure that Walter will _never_ add real 
non-nullable references.
All what will maybe come are further structs in std.alghorithm 
which blows up your code as assertions even do.
