/*

 * StaticSwitch(K)
 * =s classification
 * sends packet stream to fixed output
 * =d
 *
 * StaticSwitch sends every incoming packet to one of its output ports --
 * specifically, output number K. Negative K means to destroy input packets
 * instead of forwarding them. StaticSwitch has an unlimited number of
 * outputs.
 *
 * =n
 * StaticSwitch differs from Switch in that it has no C<switch> write handler,
 * and thus does not allow K to be changed at run time.
