This is a flag that functions in the execution environment can return to
report on the status of the operation. This way they can report an error
without forcing the entire invocation to shut down.
Cell operations like interpolate and finding parametric coordinates can
fail under certain conditions. Typically these call RaiseError on the
worklet. But that can make a worklet unstable, so provide paths where no
error is raised.
