+;;; This test is motivated by bug #195, which previously had (THE REAL
+;;; #(1 2 3)) give an error which prints as "This is not a (OR
+;;; SINGLE-FLOAT DOUBLE-FLOAT RATIONAL)". We ideally want all of the
+;;; defined-by-ANSI types to unparse as themselves or at least
+;;; something similar (e.g. CHARACTER can unparse to BASE-CHAR, since
+;;; the types are equivalent in current SBCL, and EXTENDED-CHAR can
+;;; unparse to NIL, since there are no EXTENDED-CHARs currently).
