+417: Toplevel NIL expressions mess up unreachable code reporting.
+       In sbcl-1.0.10.7, COMPILE-FILE on the file
+               nil
+               (defmethod frob ((package package) stream)
+                 (if (string= (package-name package) "FOO")
+                     (pprint-logical-block (stream nil))
+                     (print-unreadable-object (package stream))))
+       causes complaints like
+               ; in: SOME SB-C::STRANGE SB-C::PLACE
+               ;     (SB-C::UNABLE SB-C::TO SB-C::LOCATE SB-C::SOURCE)

+       Deleting the toplevel NIL, or even replacing it with 3,
+       causes the system not to complain.
