Lists contain an ordered collection of elements. Depending on usage, they may represent arrays, maps or sets.
Each element of a list may be a value of any type. Optionally, the element may have an associated key, which is also a value of any type. Keys need not be unique. An element may be retrieved or set by using either its position in the list or its key.
