Sequence -- ancestor for features that can be converted to a 'list'

Sequences are empty, finite or infinite ordered collections of instances
of a given type. Sequences may calculate elements lazily on demand.

Sequence is a 'ref' type, i.e., different sub-features may be assigned
to a field of type 'Sequence'.

Heirs of Sequence must implement 'as_list'.
