Evaluates to an AliasSeq which contains no duplicate elements.
Unique takes a binary template predicate that it uses to compare elements
for equality. If the predicate is true when an element in the given
AliasSeq is compared with an element with a lower index, then that
element is not included in the result (so if any elements in the
AliasSeq are considered equal per the predicate, then only the
first one is included in the result).
Note that the binary predicate must be partially instantiable, e.g.
