digitalmars.D.learn - Simulating rectangular array

Has anyone come up with a template that can simulate a rectangular
array and allow one to override opAssign to do special work? E.g.:

Array!(2, 4) arr;
arr[1][3] = "foo";

This would invoke opAssign in some templated struct "Array". This
would be super-easy to implement if I had an opIndex that could work
with the above syntax. I know there's a "[1, 3]" syntax but I really
need the array "[1][3]" syntax.

Maybe Philippe has this in his templates book? (If not it would be a
great addition to it)

Full-featured, tested, multidimensional rectangular arrays with slicing support (yes, like in FORTRAN): http://deoma-cmd.ru/d/docs/src/my/rarray.html (may require all files from http://deoma-cmd.ru/d/src/my/) I really thought it's just not needed, but if it is, I will make it up-to-date with current compiler and put under version control.
