Hi CL Pros,

I just came across a post on Quora https://www.quora.com/Where-did-we-go-wrong-Why-didnt-Common-Lisp-fi x-the-world/answer/Robert-Smith-9?srid=dnzK by Robert Smith where he mentions the idea of assigning some sort of "version" to Common Lisp packages in order to improve code configuration control.

This seems to me to be a pretty neat and interesting idea!

Has anyone of you explored such a concept, or know of anyone that did? Or, is anyone of you curious about it?

It's a very bad idea to do code versioning in the linker/loader in order to load two versions at the same time. Saying it makes code-reuse hard is preposterous.
