Hi Peter

Although you've quickly figured out that the functionality you need is
already there, I
do agree that the use of find_if() to express until() semantics is not
immediately
obvious. I think it is proabably a little "Aha" moment for many of us. In a
similar
vein I often find myself writing this functionality

bool exists( begin, end, value )
{
   return find(begin, end, value) != end;
}

and

bool exists_if( begin, end, predicate)
{
  return find_if(begin, end, predicate) != end;
}

So maybe there is a place for some very thin wrappers.
