@levitanong I think you'd still need to create the Delay objects outside the cell, otherwise it would create new ones each time the formula is evaluated, no? |

(cell= (= 200 cell1)) (div "two"))
(case-tpl cell4

is optional--the value is nil if no case macthes and there is no default
case (no exception is thrown).
