Returns an array holding the items of `arr' mapped through
either `ob->fun()' or 'f'. The function is called for each
element in 'arr' with that element as a parameter. A second
parameter `extra' is sent in each call if given. Principal
function:
foreach (index) arr[index] = ob->fun(arr[index],extra);
The value returned by `ob->fun(arr[.index.], extra)' replaces the existing
element in the array. If `arr' is not an array, then 0 will be returned.
