As I said, all it does is give you syntactic sugar for iota which can't even 
do as much as iota can (since it lacks a step parameter).

But my point that you're quoting has nothing to do with using .. with 
functions in general. It specifically has to do with creating a new overload 
for opSlice as Jacob suggestios - i.e. when you do a[0 .. 5] where a is an 
instance of a user-defined type. That works just fine with auto opSlice (size_t 
start, size_t end). The range type buys you nothing for that, and in fact 
would be _more_ expensive, since it would have to allocate a struct rather 
than simply passing the two indices.
