shift(+Ball)

Abandon the execution of the current goal, returning control to just after the matching reset/3 call. This is similar to throw/1 except that (1) nothing is‘undone’and (2) the 3th argument of reset/3 is unified with the continuation, which allows the code calling reset/3 to resume the current goal.
