This seems to be a miscommunication with semantics. This is not 
auto-decoding at all; you're decoding, but there is nothing 
"auto" about it. This code is an explicit choice by the 
programmer to do something.

On the other hand, using std.range.primitives.front for narrow 
strings is auto-decoding because the programmer has not made a 
choice, the choice is made for the programmer.
