To enable the first line, builtin arrays would need to be able to 
recognize arbitrary range types and do the right thing. You can 
always do this:

   float[] a = b[].transform.array;

I've got a lib to enable this syntax:

   Array!float a = b[].transform_1;
   a[i..j] = c[x..y].transform_2;

for arbitrary user-defined or composed n-dimensional range types.

where ranges are made more interoperable by common mixin 
templates which also cut down on a lot of boilerplate.
