|
|
|
|
mapping unique_mapping(array arr, string fun, object ob, ...);
|
|
|
|
mapping unique_mapping(array arr, function f, ...);
|
|
|
|
unique_mapping() evaluates the function 'f' with each element of the
|
|
array 'arr', and constructs a mapping with the return values as keys,
|
|
and subarrays of elements that returned value value as values.
