SYNOPSIS
	void set_this_object(object object_to_pretend_to_be);

DESCRIPTION
	This is a privileged function, only to be used in the master
	object or in the simul_efun object.

	It changes the result of this_object() in the using function,
	and the result of previous_object() in functions called in
	other objects by call_other().	Its effect will remain till
	there is a return of an external function call, or another
	call of set_this_object(). While executing code in the master
	object's program or the primary simul_efun object's program,
	set_this_object() is granted even if this_object() is altered
	by set_this_object(). This does not apply to functions
	inherited from other programs.

	Use it with extreme care to avoid inconsistencies.  After a
	call of set_this_object(), some LPC-constructs might behave in
	an odd manner, or even crash the system. In particular, using
	global variables or calling local functions ( except by
	call_other ) is illegal.

	With the current implementation, global variables can be
	accessed, but this is not guaranteed to work in subsequent
	versions.

	Allowed are call_other, map functions, access of local
	variables (which might hold array pointers to a global array),
	simple arithmetic and the assignment operators.
