.. efun:: closure bind_lambda(closure, object ob)

  Binds an unbound lambda closure to an object and return it. The efun can also be used to rebind an efun, simul-efun or operator closure to a different object.

  If the optional argument ob is not ``this_object()``, the privilege violation ``("bind_lambda", this_object(), ob)`` occurs.
