Function Seq

Creates a Seq.

Returns a particular kind of Seq based on the input.

• If a Seq, that same Seq.
• If an Collection, a Seq of the same kind (Keyed, Indexed, or Set).
• If an Array-like, an Seq.Indexed.
• If an Iterable Object, an Seq.Indexed.
• If an Object, a Seq.Keyed.

Note: An Iterator itself will be treated as an object, becoming a Seq.Keyed, which is usually not what you want. You should turn your Iterator Object into an iterable object by defining a Symbol.iterator (or @@iterator) method which returns this.

Note: Seq is a conversion function and not a class, and does not use the new keyword during construction.
