Are functions such as AREF specifically documented as non-generic, or
are they merely documented as being of type FUNCTION?  My
understanding was that GENERIC-FUNCTION is a subtype of FUNCTION, and
that therefore an implementor of ANSI Common Lisp is free to make any
or all Common Lisp functions generic.  And indeed, I strongly
encourage vendors to do exactly that, to the extent that efficiency
considerations permit.  Thus, AREF probably couldn't afford to be
generic just yet - at least not on conventional processors - but ELT
probably could be.
