Let me also say that I think it is important to give advice on how to
test so I think we need to say something.

Thanks. Is the N suggestion a future-proofing kind of a thing, or is
there something today that could cause such a test to pass where a
single one might fail?

In the test, if you get unlucky and there is a gc between the
definition of bx and unboxing of it then this test will pass in
correctly, I think (unless build-array complains if it gets #f?)

If `build-array' gets #f, it'll raise a contract error. I could get

On the second point, I think it may be a good idea to disallow upper case.
I presume that Eli and Matthew would have good recommendations about this?

When doing quick experiments, I've often wanted the ability to define
a new language and then use it in the same file. I thought submodules
might allow me to do this, but I've realized that I still can't.
However, in trying to do so I ran into some interesting behavior:

You can't define the reader part of a #lang in the same file and then use
it, but you can definitely define the bindings, from things like
#%module-begin and #%app on up, and use it in the same file. The following
works fine for me:
#lang racket
(module greeting racket
(provide #%module-begin)
Ah, thanks! I somehow missed the existence of the submod form.

I updated the references in the racket git repo, and I left the
unstable/lazy-require module in place with a re-export of lazy-require.
I did remove a feature that didn't seem to be in use (unquote), though,
so if someone is using lazy-require with unquote outside of the racket
git repo, that w
We make no commitments about compatibility for 'unstable', so keeping the
collection around shouldn't even be necessary.

Right, thanks. Somehow I thought it was just in a top-level collection
(I didn't read carefully enough).
Sorry,

Some improvements to DrRacket's "automatic parentheses" mode are now
available in the nightly build version and git repository. If you have
previous tried auto-parens and abandoned it, or if you have never tried it,
please do try it now!
In auto-parens mode, typing a closing parenthesis will skip
Thanks, Nadeem!
