What does the package do?

Defines a cycle data structure and functions for interacting with it.

For example I use it to manage vterm instances in Emacs:
[here](https://cs.tvl.fyi/depot/-/blob/users/wpcarro/emacs/pkgs/vterm-
mgt/vterm-mgt.el?L41),
[here](https://cs.tvl.fyi/depot/-/blob/users/wpcarro/emacs/pkgs/vterm-
mgt/vterm-mgt.el?L58-59), (etc)

Did you consider using a ring to do these things?

Thanks for pointing this out!

I could implement this with ring. I wanted a mutable and immutable
interface with arguments ordered in a way that works well with dash’s
->> macro
