! \begin{methoddesc}[object]{__init__}{self\optional{, \moreargs}}
! Called\indexii{class}{constructor} when the instance is created.  The
! arguments are those passed to the class constructor expression.  If a
! base class has an \method{__init__()} method the derived class's
! \method{__init__()} method must explicitly call it to ensure proper
! initialization of the base class part of the instance; for example:
! \samp{BaseClass.__init__(\var{self}, [\var{args}...])}.  As a special
! contraint on constructors, no value may be returned; doing so will
! cause a \exception{TypeError} to be raised at runtime.
