What steps will reproduce the problem?

View openssh-descrption-of-X11-forwarding.md

https://www.openssh.com/features.html

X11 forwarding (which also encrypts X Window System traffic)

X11 forwarding allows the encryption of remote X windows traffic, so that nobody can snoop on your remote xterms or insert malicious commands. The program automatically sets DISPLAY on the server machine, and forwards any X11 connections over the secure channel. Fake Xauthority information is automatically generated and forwarded to the remote machine; the local client automatically examines incoming X11 connections and replaces the fake authorization

Create a non-singleton class from a singleton - yargs
View README.md

A singleton makes sense when it prevent multiple access to a resource than must not be accessed in that way. But sometimes a singleton design is used because it is sufficient for expected usage. But that may block expanded usage unecessarily.

ES6 dynamic import can import a singelton module into a closure allowing a singleton to become a non-singleton class. See the file yargs-class.mjs below.
