Description

Fcf.Data.Set

Set provides an interface which is similar to the that given by the container-package. If a method is missing here that you need, please do open up an issue or better, make a PR.

Many of the examples are from containers-package. The internal representation is based on lists. We hope that a more efficient one will be used one day.
