  Not all objects can be weakly referenced; those objects which can
  include class instances, functions written in Python (but not in C),
! methods (both bound and unbound), sets, frozensets, file objects,
! sockets, arrays, deques, and regular expression pattern objects.
! \versionchanged[Added support for files, sockets, arrays, and patterns]{2.4}
! 
! Several builtin types such as \class{list} and \class{dict} do not
! directly support weak references but can add support through subclassing:
! 
! \begin{verbatim}
! class Dict(dict):
!     pass
! 
! obj = Dict(red=1, green=2, blue=3)   # this object is weak referencable
! \end{verbatim}

! Extension types can easily be made to support weak references; see section
