  In addition, a common gotcha (for me, anyway - it still gets me now
and again) is that you need to remember you're comparing "instances"
to "classes" with this method:

([value isKindOfClass:[NSString class]])

  ... not ...

([[value class] isKindOfClass:[NSString class]])

  The former is correct, the latter is what I sometimes find myself
doing (and of course it fails).
