You might also like `filtered-out` from `racket/provide` [1]. The code
sample below prints two identifiers (at compile-time):
a:x

I'm a scribble/lp2 noob for sure, but why not eliminate the need for
`code:comment` within a `chunk`?
Because I find this curious: when the `chunk` is typeset in documentation mode,
scribble/lp2 is apparently parsing the comments, because they get converted to
whitespace. So ... instead of conv
Okay, thank you for the explanation.
I totally see what you mean now by the top level being hopeless. (Or
at least I think I do.) It seems there is no way to get a meaning that
does everything we would want it to...
As a side not Matthew, I notice that you seem to be sending out two

Do you mean how can you tell what's exported given a particular module someone
has written? Or do you

Hi Greg: just in case it wasn't obvious, Jay also needed to upgrade
his Racket to a version that's newer than 6.3. You can find our
snapshot builds here if you want to try that:

I think Robby was confused by your example (which is understandable).
The `expand` function does not splice any differently than `compile`,
so `compile` behaves the same as `expand` in your example:

I tried on Windows 10 with 6.2.1 and can confirm that just installing
pict3d cases a bunch of segfaults.
If I try with the current snapshot build, I can successfully install
and run pict3d using an Nvidia GPU.

Expanding a form triggers compile-time evaluation in the sense of
running macros. Currently, though, compilation treats changing the set
of bindings at the top level as a kind of run-time effect (to be
avoided at compile time).
For example, compiling `(define x 5)` does not change the current
bind

Racket version is 6.3
My windows event log says that the module causing error in relation to Racket
is:
Greg - What version of Racket are you running?
Matthew - Do you know how to get logs from Windows crashes?
