-When data is available at the in port, it is examined. Which
-destination the datum has arrived on determines the *condition* the
-datum should be tested for and the *action* which should be taken if
-the condition holds true.
-
-The latter portion of the name of the destination (IfZero,
-If(Non)Positive, If(Non)Negative) determines the condition which the
-datum on the in port is tested for. The former portion (mux, demux,
-swap) determines the *action* to be taken if the condition tests true.
