re: After this operation completes, the contents of the symbol-package
slot of any symbol homed in the deleted package is unspecified; ...
symbol S homed in pkg P == (eq P (symbol-package S)) ?
A symbol's "home" package is defined to be the contents of its
symbol-package cell. See CLtL p.175 (about middle of page).
I guess I should have been more carefull in my statement. The problem I
was raising is that being "homed" is a satement about the symbol-package of
a symbol (and the fact that "homed" is slang), and stating that
(symbol-package x) being the deleted package and being undefined is
contradictory. The fact that you are stating something about the (previous)
state of the symbol-packge, and that kill-package may (or may not) change
the symbol-package was being muddled. In retrospect it was undoubtedly
obvious to everybody what the statement meant.
