count method only for lists?

  Hmm, what mutable sequences are left out?  Just off-hand, I can't
think of any other than lists in the core language.
  Tuples and strings are definately *not* mutable, though I expect the 
interesting methods will appear in Python 1.6.  Barry Warsaw has
already done some work to implement string methods.
