Yes, I really want to D supports multidimensional arrays, 
matrices, rational numbers and quaternions.

I believe that Phobos must support some common methods of linear 
algebra and general mathematics. I have no desire to join D with 
Fortran libraries :)

Rational numbers and quaternions have already been implemented 
are:

Satisfactory developments with matrices have here:
