Function Collection

Creates a Collection.

The type of Collection created is based on the input.

• If an Collection, that same Collection.
• If an Array-like, an Collection.Indexed.
• If an Object with an Iterator defined, an Collection.Indexed.
• If an Object, an Collection.Keyed.

This methods forces the conversion of Objects and Strings to Collections. If you want to ensure that a Collection of one item is returned, use Seq.of.

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