Changed all macros to use %READER-ERROR as appropriate. Changed #+/- to work correctly under *READ-SUPPRESS*. These macros actually do the same thing as usual under read-suppress. However, we have to make sure that *read-suppress* is nil when reading the feature expression. Also, consider feature expressions with package errors to be absent. Fixed various macros to return NIL rather than the value of *read-suppress* when *read-suppress* is true. Fixed #: to use the new READ-EXTENDED-TOKEN return value to detect colons, rather than just searching (since they might be escaped.) When *read-suppress* is true and *read-eval* is false, don't signal an error on #. When we do error for #., use the correct READER-ERROR. Changed #r to just bind *read-base* and call read, instead of doing all sorts of weird stuff to reinvent numeric reading. Check for illegal radices. Deleted some dead code once used for #=/##. Made # a non-terminating read macro character (the only one in standard CL.) So you can have symbols like foo#3, or whatever.

extra close parens are only a warning, not an error. Export READER-ERROR, and change all reader code to signal this error as appropriate (or in some cases END-OF-FILE.) If a package is undefined, or an external symbol is missing, then signal READER-PACKAGE-ERROR (a subtype of READER-ERROR.) This allows #+ to suppress this error on features without suppressing all read errors. Changed these errors to only be signalled after the whole token has been gobbled, so that unwinding out of the handler won't leave the rest of the symbol unread. Improved readtable documentation. Fixed a number of problems with #=/##. ## now works correctly with #S structures, and also detects some new error conditions (such as multiply defined labels.) Also, we now bind the specials that control ## interaction so that if someone happens to read some other stream inside a read macro, things will still work. Added Ted's changes to make INTERNAL-READ-EXTENDED-TOKEN work when there are `|' escapes. The main significance of this is that #+nil '|foo;bar| and #:|foobar| now work properly. Also change this function to recognize unquoted colons so that #:foo:bar will error, but not #:foo\:bar. Changed to not gratuitously upcase the input, and for READ-EXTENDED-TOKEN to call CASIFY-READ-BUFFER so that when READTABLE-CASE is :PRESERVE, you can #:Foo, etc.

intermediate of (- 0 x), since this is not a correct transformation. (- 0 0.0) is 0.0, not -0.0. Fixed the (- 0 x) transform to be restricted to rational args.

variable substitution can't swap it back again. Fixed multiple recoding to include many TRULY-THE's in the expansion so that the resulting shift-and-add code would actually open coded. Added comprehensive handling of arithmetic and logical identities when an arg is -1, 0 or +1. Fixed the (- 0 x) ==> (%negate x) transform to be inhibited when the 0 is more contagious than X, or is -0.0.
