-  The way that the compiler munges types with arguments together
-  with types with no arguments (in e.g. TYPE-EXPAND) leads to
-  weirdness visible to the user:
-       (DEFTYPE FOO () 'FIXNUM)
-       (TYPEP 11 'FOO) => T
-       (TYPEP 11 '(FOO)) => T, which seems weird
-       (TYPEP 11 'FIXNUM) => T
-       (TYPEP 11 '(FIXNUM)) signals an error, as it should
-  The situation is complicated by the presence of Common Lisp types
-  like UNSIGNED-BYTE (which can either be used in list form or alone)
-  so I'm not 100% sure that the behavior above is actually illegal.
-  But I'm 90+% sure, and the following related behavior,
-       (TYPEP 11 'AND) => T
-  treating the bare symbol AND as equivalent to '(AND), is specifically
-  forbidden (by the ANSI specification of the AND type).

-  (as discussed by Douglas Crosher on the cmucl-imp mailing list ca. 
-  Aug. 10, 2000): CMUCL currently interprets 'member as '(member); same
-  issue with 'union, 'and, 'or etc. So even though according to the
-  ANSI spec, bare 'MEMBER, 'AND, and 'OR are not legal types, CMUCL
-  (and now SBCL) interpret them as legal types.

-144: 
-  (This was once known as IR1-4, but it lived on even after the
-  IR1 interpreter went to the big bit bucket in the sky.)
-  The system accepts DECLAIM in most places where DECLARE would be 
-  accepted, without even issuing a warning. ANSI allows this, but since
-  it's fairly easy to mistype DECLAIM instead of DECLARE, and the
-  meaning is rather different, and it's unlikely that the user
-  has a good reason for doing DECLAIM not at top level, it would be 
-  good to issue a STYLE-WARNING when this happens. A possible
-  fix would be to issue STYLE-WARNINGs for DECLAIMs not at top level,
-  or perhaps to issue STYLE-WARNINGs for any EVAL-WHEN not at top level.
-  [This is considered an IR1-interpreter-related bug because until
-  EVAL-WHEN is rewritten, which won't happen until after the IR1
-  interpreter is gone, the system's notion of what's a top-level form
-  and what's not will remain too confused to fix this problem.]

-246: "NTH-VALUE scaling problem"
-  NTH-VALUE's current implementation for constant integers scales in
