I've been unable to break JIT backtraces in our large legacy application
under PLT 4.2.5. This is great news, since the JIT should be a big win
for us. Thanks, Matthew and the rest of PLT.

The JIT backtraces have gotten slightly better in some corner case

It's there:

What effect does the JIT currently have on debugging backtraces? Or,
how can one get some or all of the benefit of the JIT, but still
reliably get useful backtraces?
I see that DrScheme now has an option for disabling some JIT
optimizations. Should I just do whatever that checkbox is doing?
FWIW, I like to assert that the familiar "FOR A = 1 TO 10" is actually
not often needed in idiomatic Scheme. More often, you're processing a
sequence, or you're doing functional programming such that you need to
recurse anyway to avoid mutation, or you need premature exits
sometimes. One poss

Dear racketeers,
What is the reason for not offering a looping construct in racket? For
example, something like:
(loop (i 1 10) (print i))
Just for the masses, it seems simpler to use.
Any comments?

Compilation issue again.
As Matthew explained, I turned off debugging, also turned off "preserve
stack trace".
I executed the code in DrRacket and it works fine.
Then I tried in the same interaction (if I am not mistaken):

Does your call to `create-embedding-executable' work if you disable

instrumented, and that is inter

What you are looking for is in the Language dialog (bottom left button in
DrRacket), advanced parameters.
Is thee a way of adding a directory to the 'collects' path, or some other way
of specifying where Racket should look for collections?
