Details:
In FormulaAI, attempting to access a nonexistent property of an object or
nonexistent element of a list or map returns (null)0, as does dividing by
zero or invoking a math operator with non-numeric inputs. This suggests the
general principle that nullness can always be used for error trapping.
But one exception is attempting to retrieve x[0] if x is neither a list nor a
map. Doing this causes a runtime error. I suspect this is a bug and should
instead return (null)0.
