   Was that the intention?  I don't have a compiler that will deduce   
   template parameters for a supplied function to std::transform.  I admit   
   I don't know *why* I don't have such a compiler, because ISTM all the   
   necessary information is present and accounted for.   
      
   So ... can we agree on bug instead?  Because implementations are   
   falling down on the job?  Or bug, because the language defintion   
   prevents them from doing so, and forces me to supply parameters that are   
   incompatible across versions of the language?   
      
   Feature I'm having trouble seeing.
