And on the off chance that you actually want to use the contrib (and if it still works) a way which doesn't require any changes to sbcl is to redefine the make-pretty-stream function, returning a subclass of pretty-stream from it. Consequently, a clean approach would be to have (defvar sb-ext:*pretty-stream-maker* #'make-pretty-stream) in SBCL.

Oh, the thing is, swank contrib loading is currently all or nothing. So, Fabrice probably doesn't want slime-presentation-streams specifically, and I had assumed it was needed by the more basic slime-presentations contrib, which it's not.

So, the first step is to disable this dangerous patching. (Done and pushed to SLIME's repo.)

Then, we can look into re-enable this functionality using the clean approach outlined above. Opened https://github.com/slime/slime/issues/213 to track that. Patches welcome, yada yada. :-)

Thanks Stas!
