Sorry it may be my lack of knowledge or something but no one else 
seems to be responding so i will keep trying to help as best i 
can.

What do you mean by uniform syntax? do you mean you want the 
syntax to be the same as in other languages? because as it says 
on the dlang page for arrays under rectangular arrays it says 
that a[i][j] is just the way that D does it where as in c++ is 
a[i, j] but that's just one of the differences between languages 
that cant be avoided as far as i know.
