------------------------------------------------------------------------
To clarify, my comment above was not about {{null}} being regarded as {{0}}.
But rather the interpretation that {{null}} is seen as "some unknown value".
And then you _can_ argue that the result is is not unknown for {{power(null,
0)}}, because {{power(<any value>, 0)}} is always 1, whatever value is passed
as the first argument.
