Personally, I think that duplicating the test (i < max) is just as ugly.  I
would write the above as
  bool issomething() {
    for (i = 0; i < max; ++i)
      if (something) return (YES);
    return (NO);
  }
  ...
  if (issomething()) ...
which does fit nicely with the short-scope index variable rule.
