Well, I haven't inspected in detail, but have noticed at least a few
small differences:
1. The determination of which program to run for scheme is different.
I.e. the setting for emacs' default scheme mode does not have an
effect in quack. (Also it seems to remember, sometimes weirdly
wrong, what my previous scheme program was.)
2. The default syntax highlighting seems to be quite different (less
things highlighted). That's configurable though. Anyway it seems it
overrides many settings of emacs' default scheme mode without
warning (it took me quite long to figure out what the problem in #1
was).
3. Don't know how important this is, but for example C-u 100 ( works
differently :-) In emacs' default scheme mode it works, in quack it
fails after one paren with "Unbalanced paretheses".
Generally just the problem was a kind of surprise when many things in
our scheme course didn't work in Emacs in the way they had described.
But the course personnel guessed (correctly) that the problem was
quack, which they described as "weird".
OTOH I guess a lot of people like it, so it might be sensible to have
it on by default (though I'd like a way to disable it, but now I know
what hooks to look at). But yeah, I think it changes the default
behavior incompatibly in at least some respects.
