Description of issue

Lem (https://github.com/lem-project/lem) is a new editor for Common Lisp that was inspired by Emacs.

This is the presentation extracted from the README

Vision
Lem brings the distance between code and its execution state as close to zero as possible.
Users can see the results of their program while editing, without breaking their flow, and visually follow the behavior of the running code in real time.

The interface is consistently simple and easy to use without confusion.
Moreover, Lem is fully customizable, and any extensions take effect immediately as they are written.

Goals
Instantly reflect executed code inline
Visualize running code in real time
Provide a consistent UI that feels effortless to use
Maintain documentation for beginners, extension developers, and core developers.
Offer an intuitive and consistent API for extensions
Deliver a comfortable environment right out of the box

Non-goals
Rather than imitating Emacs or Vim, Lem pursues its own unique approach

I think that this package should be on Homebrew to easily follow its development.

Thanks.
