 Try typing each of these alone on a line, and you'll agree we have a
 problem:
 {{{
    %maxima
    %gap
    %gp
    %pari
    %singular
    %lisp
 }}}

 The relevant code is this in {{{misc/sage_extension.py}}}:
 {{{
     def register_interface_magics(self):
         """Register magics for each of the Sage interfaces"""
         from sage.misc.superseded import deprecation
         interfaces = [(name, obj)
                       for name, obj in
 sage.interfaces.all.__dict__.items()
                       if isinstance(obj,
 sage.interfaces.interface.Interface)]

         for real_name, obj in interfaces:
             def tmp(line, name=real_name):
                 self.shell.run_cell('%s.interact()' % name)
 }}}
