Now that we can easily turn off the message about a null value being returned, I find the indicator variables totally unnecessary code bloat.
In the rbase environment, at least, If I want to know if a null is returned I can test the actual value returned. In over 25 years of progamming rbase, the only use I ever had for the indicator variables was to avoid throwing the error to make tracing easier.
