You can easily write agents that evaluate code received over the net
(e.g. by a set operation). This can happen intentionally or it can
happen because you did not very carefully design your code (e.g. you
eval the value of a MIB variable). Obviously, this could cause
security problems and that is why you should make use of safe Tcl.
