    {{c1,c2}}alternate between c1 and c2
    {{c1,c2,…}}cycle through all ci
    {s,{c}}use s, then repeatedly use c
    {s1,{c},sn}use s1, then repeatedly use c, but use sn at the end
    {s1,s2,…,{c1,c2,…}, sm,…,sn} use the first sequence of si at the beginning, then cyclically use the ci, then use the last sequence of si at the end
    {s1,s2,…,{},sm,…,sn}use the first sequence of si at the beginning and the last sequence at the end
    {i1->v1,i2->v2,…}specify what to use at positions ik
