Comment:

 The choice of operator% was debated at the time of library design, and it
 was found better than the alternatives.

 The point you raised was considered, and considered unharmful since trying
 to compile :

 cout<<format("Choose %1% of %2%") % total-remaining+1 % total;

 fails with compiler error, the user is bound to realize her mistake when
 she forgets to parenthesize her arithmetics from time to time.
