  huh?  there appears to be some attribution problems here.  I hope I'm not
  morphing into Kent Pitman, or vice versa -- I like us separate.

| Perhaps it would be nice if the fact that the meaning of whitespace[2]
| depends on the current readtable and not on the standard readtable was
| made a little more explicit in the spec (indeed, *READTABLE* is listed in
| the `Affected By' section of PEEK-CHAR's description, but perhaps
| something could be mentioned either in the glossary or in Section 2.1.4.7
| (Whitespace Characters) too).

  I find this to be sufficiently basic to the language design that it would
  actually be confusing to add it in particular places -- one would have to
  wonder why it was added.

| Also, perhaps a standard function (WHITESPACEP &OPTIONAL readtable) that
| tests this attribute could be useful (I know a kludge that does this, but
| it is rather inelegant).

  your implementation may sport just such functions, or they might be
  macros or accessors inlined so strongly that they are not retained in the
  dumped image.
