The simul_efun object is automagically sort-of inherited by
every object. That functions that are defined in it can be
accessed just like efuns or inherited functions by every
object (except the master object). To get access to efuns that
are overloaded by the simul_efun object, you can use the
efun::function() to bypass the simul_efun (unless the
simul_efun object has defined the function as "nomask").
