modules vs packages

[ccc31807]

I read that modules are deprecated.

Is there any significant difference between modules and packages?
Other than the deprecation, of course.

Are there any significant advantages to packages over modules? If so,
what are they.

Peter Seibel says that the Perl module system is the closest to Lisp's
package system. I don't know enough about it to agree or disagree, but
with the exception of having to be careful about using (in-package) I
find that the two are pretty close.

You can find here[1] a short description on the differences between
packages, modules and systems.

Well, the main advantage is that packages exist in CL, and modules don't.

CL provides a couple of functions that you could use to ask for a module
to be loaded (REQUIRE) and signal that a module has been loaded
(PROVIDE), but the details of what exactly a module is and how to load
it are implementation-dependent, so you're on your own there.

Packages, on the other hand, are pretty well specified.
