Nice job integrating all of the bridge-related info! Thanks for all of 
your work on this.

I just had a few small comments

In Section 10.3.1, the bridge will currently also convert Lisp strings 
passed as arguments to a message send into NSStrings, so that (SEND W 
:SET-TITLE "Untitled") works.  It will also convert numbers passed as 
arguments to a message SEND to SINGLE-FLOAT where necessary and 
possible, so that (SEND W :SET-ALPHA-VALUE 1) will work.

In 10.3.2, (SEND V1 :SET-BOUNDS (SEND V2 'BOUNDS)) should probably be 
(SEND V2 :SET-BOUNDS (SEND V1 'BOUNDS)) to be consistent with the 
previous example using SLET.


In 10.6, probably no need to mention (MAKE-OBJC-INSTANCE "XXX" . . .), 
since you can always use (MAKE-INSTANCE (@CLASS "XXX") . . .)

In 10.6, the statement that the "INIT" prefix is optional in 
initializer keywords works for MAKE-INSTANCE as well.  Since I am 
suggesting removing any mention of MAKE-OBJC-INSTANCE above, I would 
recommend that the examples here be changed to use MAKE-INSTANCE.

Note to self: The use of (@METACLASS XXX) to declare that the type of 
something is a metaclass of class XXX should be replaced by the new 
NS:+XXX syntax someday (this will require a change to
