It's awkward. How about having `read-language' (or a variant?) somehow

I committed a variant of this that is probably closer to your earlier
version.
There's no point specializing the message to phase -1, because no
expression is compiled in that phase. Also, as you suggested before, I
prefer leaving out phase 0, since that makes the message simpler for
the common

I don't think this process pulls in other planet packages, but it

No,
I'm impressed that you got it working, and I'd appreciate patches for
what you have so far.
To test, run

Yes, the JIT problem is surely LP64 vs. LLP64; the JIT generates 64-bit
operations for data structures that contain `long's. I think we'll

The example below is independent of Typed Scheme.
The problem is that a macro introduces `f' by itself. As soon as that

The result seems wrong, particularly since
That was a leak. The implementation of `scheme/async-channel' uses
`thread-resume', which created a strong link from its first argument to
its second argument. The link should be weak if the thread is blocked
in some way other than being explicitly suspended.
The bug fixed is now fix in SVN.
I finally saw the DrScheme-loading error, and it's now fixed.
