| Being deprecated by ANSI standard doesn't help it either.
But don't forget that all of the "deprecated" features in
CLHS are still *required* to be present in an implementation
that purports to be a "Common Lisp".
1.8 Deprecated Language Features
Deprecated language features are not expected to appear
in future Common Lisp tandards, but are required to
be implemented for conformance with this standard; see
Section 188.8.131.52 (Required Language Features).
