SYMBOL-MACROLET bugs reported by Peter Van Eynde July 25, 2000:
- a: (SYMBOL-MACROLET ((T TRUE)) ..) should probably signal
- PROGRAM-ERROR, but SBCL accepts it instead.
- b: SYMBOL-MACROLET should refuse to bind something which is
- declared as a global variable, signalling PROGRAM-ERROR.
c: SYMBOL-MACROLET should signal PROGRAM-ERROR if something
it binds is declared SPECIAL inside.

there might be any user-level symptoms.)

- a latent cross-compilation/bootstrapping bug: The cross-compilation
- host's CL:CHAR-CODE-LIMIT is used in target code in readtable.lisp
- and possibly elsewhere. Instead, we should use the target system's
- CHAR-CODE-LIMIT. This will probably cause problems if we try to
- bootstrap on a system which uses a different value of CHAR-CODE-LIMIT
- than SBCL does.

Inconsistencies between derived and declared VALUES return types for
DEFUN aren't checked very well. E.g. the logic which successfully
the first time around, until regression tests are written I'm not
comfortable merging the patches in the CVS version of SBCL.

- As reported by Arthur Lemmens sbcl-devel 2001-05-05, ANSI
- requires that SYMBOL-MACROLET refuse to rebind special variables,
- but SBCL doesn't do this. (Also as reported by AL in the same
- message, SBCL depended on this nonconforming behavior to build
- itself, because of the way that **CURRENT-SEGMENT** was implemented.
- As of sbcl-0.7.3.x, this dependence on the nonconforming behavior
- has been fixed, but the nonconforming behavior remains.)

(DESCRIBE 'SB-ALIEN:DEF-ALIEN-TYPE) reports the macro argument list
incorrectly:
It should be possible to be much more specific (overflow, division
by zero, etc.) and of course the "How can this be?" should be fixable.

- There's some sort of problem with aborting back out of the debugger

- telling the debugger to ABORT doesn't get you back to the main REPL,
