Hi Robert,

Thanks again for the feedback.

Sorry, I don't understand what you mean with this, can you elaborate a
little bit?

If I understand you correctly, in the first link I've sent there is
an Emacs snippet that does that:

https://github.com/joaotavora/sly/pull/366/files

It works, but the point is that ideally all users should not have to
roll their own trick: it would be greaet if ASDF (because it's the
common denominator of all Lisp implementations) would provide a helper
that does this job, thus saving some hassle to the users.

Does that make sense?
Interested in your thoughts.

Cheers!
