The ability to define a function on a neighborhood,
where the neighborhood is defined by relative coordinates,
is useful other places too. (E.g., agent based modeling.
Here the output should be a new array of the same dimension
with each element replaced by the value of the function on
the neighborhood.) I am also interested in learning how
people handle this.
