• Common reactive operations like combine, merge, aggregate, etc.

• Stateless operations: store result in own state variable instead of get_state on operation, no support for is_valid then

• OK Stateful operations: use get_state to get value from operation

• IfExecuted with inputs from different sources should NOT be possible, will never be executed

• Should there be validation policies to check before executing a node, independent of the inputs? (e.g. check if all inputs are valid)

• implement or remove val_policies

• Feature to collect stats about nodes: number of calls, time spent, average time, max time, etc.
