I agree invertibility of backquote is desired. But users can define their
own read macros. Why don't we supply a mechanism to allow users to define
inverses of read macros, and have system supplied ones also use this
mechanism, and have the pretty-printer print the inverse?
Which reminds me--there hasn't been any discussion of Waters's modification
of FORMAT and streams to do pretty printing on this mailing list. It seems
there was some accord back in September that his proposal was reasonable.
This would be a good example of a non-portable, compatible extension to
Common Lisp; we should try to agree on this now so that its future inclusion
will be easy.
