My concern is that this shouldn't compile in the first place. What is
xyz?, Is it a free function? Is it a member variable or function?  In
my mind it is neither of the two so why does it compile?

Oh, but that's precisely the point of opDispatch. ;) It offers a
mechanism to respond to any members that are not found. See the spec
for an example: http://dlang.org/operatoroverloading.html#Dispatch


Exactly. opDispatch catches calls to missing methods and acts based on
method name which it gets as a string at compile time. In this case, the
idea is this:

         auto v1 = Vec!4(4, 5, 6, 7);
         auto v2 = v1.xyz;   // => Vec!3(4, 5, 6);
         auto v3 = v1.wx;    // => Vec!2(7, 4);
         auto v4 = v1.wxx1;  // => Vec!4(7, 4, 4, 1);

Okay, got it. Thanks to both you and David for the clarification. A bug report was filed:
