You mean StringInputStream and StringOutputStream, right?

I don't really have any objection, but I'm about to release 0.21.0, so
please hold off for a day or so, until you see the 0.21.0 announcement
on this list.

That said, I do have in mind one day to do a proper re-implementation
of streams at the Java level.

I think this will be something like either Gray streams or Allegro's
simple streams (although maybe not identical to either of those), but I
haven't really thought it through yet. There's a mailing list for this
subject (streams-standard-discuss at common-lisp.net); I'd prefer to
follow some existing (or at least proposed) standard rather than just
making it up as I go along, but I'm willing to do the latter if all
else fails.

(In addition to everything else, ABCL should really support Java's
flavor of Unicode, and this isn't possible with the current low-level
stream implementation.)

In the meantime, we should do whatever is necessary to make slime-for-
emacs work well, and I may end up using the slime streams for slime-
for-j too, at least in the short term.
