I've added "submodules" to a version of Racket labeled v5.2.900.1
that's here:
https://github.com/mflatt/submodules
After we've sorted out any controversial parts of the design and after
the documentation is complete, then I'll be ready to merge to the main
Racket repo.
Why Submodules?

When I wrote "inlining", I should have written "function inlining".
The `compile-context-preservation-enabled' parameter doesn't affect
propagation of non-function constants (which I incorrectly called
"folding" in my previous message); it affects only function inlining.

You can use a `file' module path to allow ">" in the name:
(require (file "file-with-lo>ng-name"))
A ">" isn't allowed with the portable relative-path form, because ">"

The bytecode compiler now supports cross-module inlining of functions.
As a result, for example, `empty?' and `cons?' should now perform just
as well as `null?' and `pair?'.
To avoid expanding bytecode too much, the compiler is especially
conservative about which functions it chooses as candidates

I think you could get this behavior by creating a manager thread when

you can get the effect of a primitive by using `ffi/unsafe/atomic'.

I've fixed the problem that caused `raco exe' to not terminate.
I doubt that the older problem you've seen is fixed,

I think this is a good change for the next language, but not for `#lang
racket'.
As confusing as the current `integer?' may be, I think its definition
is deeply wired into our code, tests, and documentation. I may guess
wrong, but my best estimate of the hassle for this change is that it's
too muc

We use "channel" for asynchronous channels, too, such as
`racket/asynch-channel'. Since all place channels are

After looking into this, I conclude that the test is faulty, but that
it also highlights a bug/limitation on Windows:
* The test
The `with-limit' test is not completely deterministic. It's looking for
an out-of-memory exception, and you got an out-of-time exception,
instead. That sometimes happens if the machine is loaded or otherwise
distracted.
The `find-seconds' test may be wrong or it may be a bug. I see it for

The `racket/contract' and `racket' modules now provide `contract-out',
which is a `provide' form for contracts. Use
(provide (contract-out ))
instead of
(provide/contract )
There's one difference between `(provide (contract-out ))' and
`(provide/contract )': contract ex
Yes, that's all correct. Although Microsoft now simply calls it the

I've pushed a fix for the problem with forward slashes in PLTCOLLECTS.
I haven't been able to provoke problems with version mismatches or
`raco link' not working for a tool. Here's what I tried.
Environment:
git checkout & build in c:\matthew\plt
5.1.3 install in "c:\Program Files\Racket-5.1.3"
It looks like the call in C might have been in a thread other than the
thread where Racket was started. In that case, when scheme_post_sema()
tries to cooperate with the GC, then it would end up with a NULL
pointer for the Racket GC information of the current thread.
In particular, since you're as

I think Racket won't work on ia64 because we never worked out how to
deal with its multiple stacks.

I think the problem is that I changed xform without adjusting the
version number as I should have.
A fresh build directory or throwing out
"/racket/gc2/xform-collects" and "/racket/gc2/xsrc"
should avoid the problem.
[I planned to push a change that adjusts the version number, but I
