I'm not ranting how unusable it is here; I'm saying what I consider to
be a mistake in retrospect that other languages IMO should learn from as
they build their namespacing.

Thirty years ago, people did not really care about namespace pollution,
namespace versioning, or even about library versioning much; nowadays,
it turns out to be a big problem, as someone mentioned earlier in the
thread.

Common Lisp, including ASDF and Quicklisp, has no good solution for
library versioning, let alone package export or namespace versioning.
All standard Quicklisp dists are just bundled together after verifying
that they load on a single image, and version pinning of individual
dists is left as an exercise for the programmer. (Even Alexandria stayed
on version 0.0.0[0] for *years* before I've actually asked it to be
fixed[1].)

It is not *too* much of an issue since the Common Lisp world is not a
very big one compared to other programming languages, but as the CL
ecosystem grows, I expect that it'll start to become a somewhat pressing
matter eventually.
