Hi Jan,
That's a nice idea. Something similar --- but in a restricted form ---
is used internally to implement various primitive events. I think I see
how to generalize it to work with more arbitrary events and non-atomic
replace functions.
There could easily be a catch that I'm overlooking, but
(almost always) and x86 doesn't have this problem.

Recall that we added `@history[...]` to `scribble/manual` so we can
document the addition of new modules, bindings, arguments, command-line
flags, etc.
It's easy to forget to add a note, and we have no good way of checking
that `@history[]` notes have been added where needed. On the plus side,

How about `(hash-set #hash() k v)`?
(I probably should have been more careful in defining `hash` to allow
it to return a constant when given 0 arguments.)

Just to clarify a little, `--pdf` files generated on Robby's machine
look fine in Preview on my machine, and `--pdf` files generated on my
machine look bad in Preview on Robby's machine. The machine dependence
is in how the output is viewed, and not what is

Assume this is a style of some sort (I should be all set after that).

My guess is that this is related to a transition from 32-bit branches
to 64-bit branches in JIT-generated code, which happens onx x86_64 when

Yes. Please use rsync from mirror.racket-lang.org instead of

We moved download.racket-lang.org to an S3-hosted site, while

Ok, I see. I'll revise my comment to this would be better done with a
more general form of type inference, leaving out the claim of where
that inference should live.
I don't currently know how to do it other than building inference into
the complier. Matthias's plug-in rules sounds like a point

The result of `expand` does not keep track of it source. You may want
