After working in C/C++ on Windows for nearly 25 years, for some reason

I settled on PLT Scheme. I liked the IDE and docs.

I dont disagree but linux still has some mild annoyances with my

You can build on Windows with VC Express. You just cant use the
build.bat script bc there's no devenv. If you use the vcbuild command
line tool that comes with VC express, you get some errors.

Oh I didn't realize that, I thought it still experimental-ish. That's great.
Building Racket on Windows has seemed daunting. For the same reasons

Thanks, this is helpful. I don't use macros very much, and I've been trying to

something that could just as easily be done with a function.

We don't yet have a 64-bit build for Windows on the download pages, but
Racket builds, runs, and is supported for 64-bit mode in Windows (Vista
and up).

On Windows 7 I would if I could. A 64-bit build of Racket for Windows
could utilize more than 2 GB.

I notice that the Wikipedia article for Racket (a little sparse in my opinion)
http://en.wikipedia.org/wiki/Racket_(programming_language)
asserts that Racket was the first higher order language to use a contract
system, but that statement has been flagged as needing a citation to back it

The stock smtp-send-message MIGHT work with Gmail (I haven't tried)
but it definitely will NOT work with hosted Exchange.
HTH.

It looks like Gmail supports the port 587 STARTTLS approach exactly
the same as does hosted Exchange (Gmail also supports connecting using
SSL on port 465).
So you can use the same approach (port 587 STARTTLS) testing against
both servers:

I'm aware of. I'm not sure if Racket exploits the later, but it should

For the last four months, I've been using the 64-bit Racket on my spiffy new
