It's not arbitrary. It keeps the language simple and easy to 
read. After all the entire auto keyword is just there, because 
the compiler needs a keyword and in loops it's clearly defined 
what the type will be.
You don't complain that `int int` is forbidden, or do you?

I guess you are frustrated because you are used to this pattern 
from other, inferior languages. I bet you will soon start to 
appreciate the syntactic sugar that D provides.
