with-hash-table-iterator in file macros.lisp results in what appears to be unnecessary consing.

Consing is reduced by adding ,state to the list of dynamic-extent declarations, as shown below.

(defmacro with-hash-table-iterator ((mname hash-table) &body body)

"WITH-HASH-TABLE-ITERATOR ((function hash-table) &body body)

provides a method of manually looping over the elements of a hash-table. FUNCTION is bound to a generator-macro that, within the scope of the invocation, returns one or three values. The first value tells whether any objects remain in the hash table. When the first value is non-NIL, the second and third values are the key and the value of the next object."

(let* ((hash (gensym))

(keys (gensym)) (values (gensym)) (count (gensym)) (state (gensym)))

`(let* ((,hash ,hash-table)

(,count (hash-table-count ,hash)) (,keys (make-array ,count)) (,values (make-array ,count)) (,state (vector ,hash 0 ,keys ,values (enumerate-hash-keys-and-values ,hash ,keys ,values))))

(declare (dynamic-extent ,keys ,values ,state)

(fixnum ,count))

(macrolet ((,mname () `(next-hash-table-iteration-1 ,',state)))

,@body))))

Basically this happens because coerce-to-complex works on the literal type specifier instead of the canonicalized ctype. I've included a small patch to remedy this.

Hi,

I have installed the latest ccl:

$ uname -a
Darwin localbox 11.4.2 Darwin Kernel Version 11.4.2: Thu Aug 23 16:25:48 PDT 2012; root:xnu-1699.32.7~1/RELEASE_X86_64 x86_64

Welcome to Clozure Common Lisp Version 1.9-r15759  (DarwinX8664)!

And I'm having issues with conditional read time (#+) working incorrectly. You can reproduce the issues trying to load nibbles or ironclad:

nibbles:

$ /usr/local/ccl-1.9/dx86cl64

? (quicklisp:quickload "nibbles" :verbose t)
To load "nibbles":

    nibbles
; Loading "nibbles"
Read error between positions 70 and 91 in /Users/rogersm/quicklisp/dists/quicklisp/software/nibbles-20121125-git/sbcl-opt/nib-tran.lisp.
> Error: There is no package named "SB-C" .

> Type :GO to continue, :POP to abort, :R for a list of available restarts.

> Type :? for other options.

A possible solution is to apply this patch to nibbles package:

sbcl-opt/nib-tran.lisp
@@ -2,8 +2,9 @@
 
 (cl:in-package :nibbles)
 
-#+sbcl (progn
+#+sbcl
 
+(progn
 (sb-c:deftransform %check-bound ((vector bound offset n-bytes)
 				 ((simple-array (unsigned-byte 8) (*)) index
 				  (and fixnum sb-vm:word)

But nowhere in Hyperspec says a return carriage should be added.

ironclad:

$ /usr/local/ccl-1.9/dx86cl64

? (quicklisp:quickload "ironclad" :verbose t)

Both issues do not occur in:
