Re: [Sbcl-devel] Disappearing code in 'compiler/dump.lisp' through incorrect use of read-time conditional

[Douglas K. <do...@go...>]

And by the way I think CCL's issue of non-reachable TYPECASE is totally
bizarre.  I mean a "warning" is "warning", right?
But it's "Fatal".

File foo.lisp:
=========
(defun foo (x)
  (typecase x
    (integer 1)
    (fixnum 2)))


? (compile-file "/tmp/foo.lisp")
(compile-file "/tmp/foo.lisp")
;Compiler warnings for "/tmp/foo.lisp" :
;   In FOO: Clause (FIXNUM 2) ignored in TYPECASE form - shadowed by
(INTEGER 1) .
#P"/private/tmp/foo.dx32fsl"
