Your new example doesn't show it better, it's the only one you've given 
that shows it at all.  What you had originally was

   auto a = [1, 2, 3, 4, 5, 6];
   auto b = delete(a, 4);

   assert([1, 2, 3, 4, 6] == b);

which shows the removal of the element at index 4, not the element with 
value 4.

But there are further questions to be answered:

- What do you want it to do if the value isn't in the array?  Just 
return the original array, return a copy of the original array, or throw 
an exception?

- What do you want it to do if the value is in the array more than once? 
  Remove the first, remove the last, remove all of them, or pick one at
