While the example input here is not precise about newlines, if someone
finds a real-world example that does not use CRLF properly, then Racket
might want to be more liberal in what it accepts here.

I think the main problem is that the input string has LF newlines, and
it needs to have CRLF newlines. You'll also want a terminating CRLF.
With those changes, then `(message-fields inner-message)' instead of
`(entity-fields inner-entity)' will get you the headers that include
"X-Riak-Vclock: ..."
I'm having difficulties parsing mime multipart messages (probably I
missed something in the docs again). I have this code:

My applications are mostly in Statistics/Data Analysis. Rather than dealing
with a single, massive data set, I often have many medium-sized ones. I
find myself applying in R or Python large amounts of maps, reduces, filters
and other list manipulations that I believe Racket can perform more

Yes to the quick tutorial, no to the other two, as they're not my intended

I'm guessing this is a contract issue, but it looks to me like calls from
racket into typed/racket are slow. To wit:
#lang racket/load
(module a typed/racket
(provide float-add)
(: float-add (Float Float -> Float))
(define (float-add a b) (+ a b))
(printf "a million in-module typed adds\n")

On my mac, the window summoned by a double-click after running Performance
Report has no close box, and no close buttons, and no obvious way to dismiss
it. It turns out that choosing "Racket > Quit" from the menu gets rid of it,
but on a Mac, this is *severely* unintuitive, as it appears that y
formlet-display returns a forest of xexprs
Templates are about writing the text directly as a string.
Whenever you want to include any non-string content in a template,
you'll need to render it as a string. In the case of the result of
formlet display, that means something like

Right - thanks!

All unions get flattened, so generally there are multiple possible
reconstructions of larger types. It's a set-cover problem - NP-complete. But
hey, proving well-typedness in TR is co-NPC, so... heh. I think Vincent has a
greedy algorithm to do a good job of this, but apparently it hasn't been m

Hi,
sorry for coming with a web server-related question again already, but I have
problems figuring out how to display formlets inside templates.
I've tried several ways, the latest being:
...
(send/suspend/dispatch
(lambda (make-url)
(get-main-template #:title "start"
Just look at this! I’ve never thought that Internet can be so interesting!..

Thanks for your responses to the MysterX poll. Based on those
responses, here's the plan:

(i.e. after the next release). No one claims to be using the part
