This module seems only used to determine the type of each datum for
assigning a colour:

+(define *colorize-list*
+  `((,<integer> ,color-integer light-blue)
+    (,<char> ,color-char brown)

The datums tested for are all primitives.  For reference, the
“class-of” operator is more-or-less equivalent to:

  ((integer? x) <interge>)
  ((char? x) <char>)

Is there some advantage to using the GOOPS classes rather than
equivalent predicates, which are more universal?  Of course, the order
of the tests matters highly in both cases.

There is already a guile-lib module (ansi term-color) that has a
particular syntax and defines the codes.  It would be excellent to
make use of it here, or at least share the syntax and avoid some
