Description

It would be nice to have a Lazy List implementation here.
Apart of the interesting abstraction it provides for users of this library, it might be useful to use it as underlying type to implement some seq traversals, which require lot of cons operations.

One possibility is to import the implementation from the old PowerPack.

Research direction

Start by reviewing the issue and the referenced implementation from the old PowerPack. Compare the proposed lazy-list abstraction with the existing seq traversals and their cons-operation needs. The issue does not define an API, target files, tests, or completion criteria, so those must be established before implementation.
