My suggestion was to call bind just once at the beginning of function 
and before any call to yield.
If you want to ensure that the bind has been done, you could request 
that yield is provided by the result of the bind operation, as e.g.

     int f( caller_t & c, strg & s, int x) {
        auto b = c.bind( s, x); // s and x are now used to store the next calls.
        b.yield( 7); // alternative b( 7)
        // here s and x have been reassigned
  }

Best,
Vicente
