I like this. The Stepper becomes available as an aid to help you
answer questions about how things came to be. It is indeed often the
case that I lose the plot when stepping forward and hence go to the
end and work backward; this could put you there right away.

Rename Use the language declared in the source option to Declared
(if first-week CS students don't confuse that with declarative language)?
Automatic or Detected sound a little bit grandiose, but aren't too
bad either.
Ideally, only students ever have to change this setting, or even be told

Understood, and agreed. Thanks!
Anyone else have comments/suggestions? I really like Robby's UI
suggestion and am treating it as the lead contender.

Yes there is -- the usual two diff flags can be used:

Robby's idea of allowing students to choose how a RUN actually worked occurred
to me too but I had a different behavior in mind. Instead of opening a separate

I can see how to do what Mattgias is suggesting at the snip level (so
not as bad as I made out) but you won't get nested scroll bars so you
might not like it.

I don't know if anyone cares about this, but I made a reader and #lang
language for the alternate syntax I came up with (direct, obvious
conversion to s-exp but allows writing fewer parens). Implementations
are usually better appreciated than mere proposals. You can get at it
here:
One of the examples reads:
{lambda: [x] x(x)}
(lambda: [x] x(x))
Notice the curly brackets in the first line.
I am not sure I like this.
Nevertheless a nice idea to use colons in order to reduce the number of
parentheses.

At the moment there is a barn-door sized security hole in DrRacket,
whereby it will take any snip% instance from the user's program and
just display it in the repl. You can exploit this for Good by making
the current-print of your language turn some values into snips (like
images and things).
That seems like the wrong point of integration. If I have
(define v complex expr)
(check-expect (g v) h)
then simply stepping into (g v) may not at all be enough. If the
stepper forced people to rewrite their programs just for steppability,
that should be considered a bad design.

Well, that makes sense.
I'm just saying that, in an ideal world, when using the DR, you're
much more writing tests that typing things into the REPL. So it would
be good if the stepper could support that better in some way.
