- This function takes the elements of a and splits them into two groups. The

|
first group remains in a and the second group is put into b. The ordering of
|
|
elements in a is preserved. In particular, concatenating #a with #b will
|
|
reproduce the original contents of a.
|
|
- The elements in a are moved around using global swap(). So they must be
|
|
swappable, but do not need to be copyable.
