Subject: Re: fixing things
It seems that +INTERNAL-/'-MACRO now calls a read entry which calls
the read hook. . . . The read hook has semantics of being a "toplevel"
call and is allowed to do things like flush the character trailing a
character. This isn't right for a recursive read.
It's not entirely clear what the purpose of this read "hook" is -- the
toplevel hook is another feature (READ-*-EVAL-PRINT and *-READ-EVAL-PRINT) --
and furthermore, its not clear that we've resolved the READ-PRESERVE-DELIMITERS
problem for maclisp; but your comment seems right, that READ rather than
(LAMBDA (X) (COND (READ (FUNCALL READ X)) ((READ X))))
is what is desired. So I've again patched it accordingly.
