A agree. I've tried to get into the convoluted STL algorithm stuff, but the number of absurd hoops one has to jump through to use for_each just isn't worth the headache. I think the problem is that, like anything else, loops are dangerous in the hands of a stupid person. But all this solution does is to make replace one kind of potential error with a few more.. and with the resulting overhead of having to learn how the screwball STL algorithm syntax works.

Yeah that's my impression, too. This seems to be complexity for complexity's sake, or possibly just to distance itself from anything obvious non-STL. ----------------------------- All truth passes through 3 stages. First, it is ridiculed. Second, it is violently opposed. Third, it is accepted as being self-evident.
