I'm not following whether you don't like the implementation or
documentation. My patch just documents the existing implementation.
The implementation has been in for a while (GvR checked in Alex's
patch for www.python.org/sf/724135 ). The news item reads:
- bool() called without arguments now returns False rather than
raising an exception. This is consistent with calling the
constructors for the other builtin types -- called without argument
they all return the false value of that type. (SF patch #724135)
