It's called by multi-dimensional opIndex (or opSlice and perhaps 
others?; can be very complicated :) ).

import std.stdio;

struct S {
      property size_t opDollar(size_t dim)() {
         writefln("Called for dimension %s", dim);
         return dim;
     }
     auto opIndex(A...)(A args) {
         return 42;
     }
}

void main() {
     auto s = S();
     s[$, $];
}

Called for dimension 0
Called for dimension 1
