```
1> Cache0 = fifocache:new(10).
{fifocache,#{},{array,10,0,undefined,10},10,0,false}
2> Cache1 = fifocache:push(key0, value0, Cache0).
{fifocache,#{key0 => {value0,1}},
           {array,10,0,undefined,
                  {key0,undefined,undefined,undefined,undefined,undefined,
                        undefined,undefined,undefined,undefined}},
           10,1,false}
3> fifocache:lookup(key0, Cache1).
value0
