SBCL to wager that this (undefined in ANSI) operation would be safe.
3:
+ a:
ANSI specifies that a type mismatch in a structure slot
initialization value should not cause a warning.
WORKAROUND:
Such code should compile without complaint and work correctly either
on SBCL or on any other completely compliant Common Lisp system.
+ b: &AUX argument in a boa-constructor without a default value means
+ "do not initilize this slot" and does not cause type error. But
+ an error may be signalled at read time and it would be good if
+ SBCL did it.

6:
bogus warnings about undefined functions for magic functions like
SB!C::%%DEFUN and SB!C::%DEFCONSTANT when cross-compiling files
(see bug 203)
+ c. (defun foo (x y)
