Thanks, these emails explain things fairly clearly.
It's worth noting that as more functions get added to racket, it becomes
more likely to trip across this. In particular, we hit this only because
range was added between 5.2 and 5.3.

Hi,
I'm running DrRacket version 5.2.
In Pretty Big, I get the following error message.
The variable cl is highlighted in the definitions window, and in the
interactions window the following text is displayed (partially in red).
cl: expected cl in: cl
In R5RS the code runs fine.

Yes, in my non-Racket-expert view, the core issue is certainly interactions
between toplevel and the module system. It seems unfortunate at best that
we have:
Welcome to DrRacket, version 5.3 [3m].
Language: racket; memory limit: 512 MB.

(if (> lo hi
I forgot to add one rationale for having a context dependent meaning
of define-values. With the current setup, you can write
(module foo some-lang
(define (range ...) ...))
without worrying about whether range is defined in some-lang or not.

The expansion in the repl
I believe there is a Unix system call (available through the C interface, but
not through a shell command) that can modify the environment of the parent of a
process. I think it's used in the implementation of the commands that
manipulate the shell's own environment. But IIRC, by design, a proce
Thanks, David. I would be interested in someone walking through how this

Up until recently the following worked for me. Create a custom keybindings
file. Add the following line.
(keybinding "c:\\" (λ (editor evt) (send editor insert "λ")))
And a Ctrl:\ would insert a λ for me. Recently this has stopped working as
reported below. Any ideas on how to bring it back?
Hello,
could anybody explain me how to get a property with arguments.
WshEnvironment Object:
Object.Item(natIndex)
This does not run :

The environment is something that belongs to a process (and its
children). The way to change the system wide defaults on windows (from
a program) is to change the registry keys that hold them. Remember that

No, and there can't be such a command, because the system itself doesn't
support it (as before, my remarks
