The cell can be automatically populated as needed by the function implementation upon node instantiation/deserialization. > > @sadboy that is a (really) good idea BTW I thought more about this and one challenge is that currently the scalar function implementations that are passed around may be shared -- so using interior mutability would get confusing as each function invocation would be from the same instance of the function -- This is an automated message from the Apache Git Service.
