it is all about syntax, and it's not just pair<iterator,iterator>
but users own types too.

we could demand that

using std::make_range;
for( const suto& r : make_range( expression ) )
    {...}

was the generic solution, but the amount of work it takes to include 
<iterator>
is certainly not great.

also, member functions are worse at forwarding than free-standing.
