This stream sends strings to the REPL buffer, where it will appear as
a REPL result, using (:write-string MESSAGE :repl-result)
In normal SLIME, there is no *big* difference to sending these
:write-string messages directly, which is what
SEND-REPL-RESULTS-TO-EMACS does, but see below.
When swank-presentation-streams is loaded, however, we use the stream
to support nested presentations in the REPL result, such as those that
you get when you type
(list (find-class 'standard-class) (find-class 'standard-object))
I remark that there would also be a benefit in using the stream in
normal SLIME without presentation streams: Large REPL results, like
will be sent through the stream, so it will be sent using many small
:write-string messages rather than one huge message, so we can see the
beginning of the output in Emacs before Lisp finishes printing all of
Unfortunately it seems there is currently a bug in SLIME that keeps
repositioning point to the end of the buffer while this output
appears, so it is not possible to scroll up during this time...
