Error: xxx is not an lvalue

[Unknown W. Brackets]

This code works fine (D 2.x only):

class Test
{
   private int[int] _testMap;
   public ref int[int] testMap() {return _testMap;}
}

void main()
{
   Test test = new Test();
   test.testMap[0] = 1;
}

Note the "ref".  Otherwise, a value is returned which is not modifiable. 
  This will also fix test.array.length.  Nothing wrong here, no creepy 
bad temporary property problems.

I suppose you could also try returning a pointer to an associative array 
(e.g. with &) in D 1.x.
