Hi again!

Thanks for your proposal, it brings up some interesting ideas.

Have you looked at lisp-utils.scm?  I think it incorporates some of your ideas
already.  It could perhaps be generalized following your ideas so that it works
for all Lisps out of the box.

Question: Are .fasl files compatible across Common Lisp implementations?  If
not, then what's your suggestion?

I have a few more questions:

> The idea is simpler packaging, through a system called PACKAGER, which would provide a very
> high-level and exhaustive declaration of an entire Common Lisp package or collection of packages

By "system", do you mean a _build system_ or something else?

> This location could default to "~/.common-lisp/" and be controlled through an environmental
> variable, with a name such as GUIX_COMMON_LISP_HOME.  

We want to install libraries in the store.  Why do you suggest we put it in the
user's home?

> As the files actually loaded by this system

Sorry, I don't understand how your proposal would eliminate the POSIX-assumption
issue.  Can you provide an example?

Cheers!
