[alrs]

Several of the functions in pkg/validation/internal properly check to make sure that they haven't received a nil pointer, but they imporperly do it only after first attempting to dereference the pointer.

@grokspawn it would be good if you could 👀 this. I don't know if there was a reason to set the name in the result.
