  Minor fix-ups to named tuples:

  * Make the _replace() method respect subclassing.

  * Using property() to make _fields read-only wasn't a good idea.
    It caused len(Point._fields) to fail.

  * Add note to _cast() about length checking and alternative with the star-operator.

  r59731 | jeffrey.yasskin | 2008-01-05 09:47:13 +0100 (Sat, 05 Jan 2008) | 11 lines

  Continue rolling back pep-3141 changes that changed behavior from 2.5. This
  round included:
   * Revert round to its 2.6 behavior (half away from 0).
   * Because round, floor, and ceil always return float again, it's no
     longer necessary to have them delegate to __xxx___, so I've ripped
     that out of their implementations and the Real ABC. This also helps
     in implementing types that work in both 2.6 and 3.0: you return int
     from the __xxx__ methods, and let it get enabled by the version
     upgrade.
   * Make pow(-1, .5) raise a ValueError again.
