When I run the plain recursive vs. the accumulator version of sum with
g-series, I get the same result, which the text says isn't supposed to
happen. Code attached. What am I missing?

The */forget functions delete continuations from the server table.
There is no server table for stateless servlets[*], so those functions
don't do anything extra. You could use server state on your own to do
something similar.

[*] Actually they do, but that's just for the native components, e
Final question for today:
Are stateless servlets supposed to be "forgettable"?
Using stateful servlets I can use e.g. redirect/get/forget
to render a concluded "session" (relatively) inaccessible.
Is there a similar mechanism for stateless servlets that I
am just not seeing?
Thanks,

In Windows,
esc-ctrl-; comments
and
esc-ctrl-= uncomments
This is for emacs keybindings mode. I dont know if it works when emacs
keybindings are off.

hehe ... sounds like a challenge :-)
I'll be a good boy then, and use local from now
FWIW, there have been some (somewhat) recent changes to the way
internal definitions work that make them behave much better. In
particular, if you have a bunch of internal definitions with
expressions interspersed, then they all go in the same (recursive)
scope.

Hi.
In the web-server related documentation, I see the preferred way to
create local procedures as
(define (start request)
(local ((define (response-generator...))
(define (some-handler...)))
(do-something-with-these)))
Another way to create local procedures is

In other words there aren't shortcut keys ("accelerators") per se
bound to these commands. But you can use the keyboard to choose an
item from a menu, as usual in Windows. (This is the one biggest thing
I miss when I'm using OS X. (No, pressing C+F2 arrow arrow arrow arrow
... isn't the same :) )).

I've dug into this deeper and it turns out that it is an error in the
Web Server. The code that sets up servlets abuses the fact that the
servlet dispatcher sets the exit-handler in a particular way (that is
actually a violation of its unchecked contract.)
I've made a fix and will push it shortly.
Ya, this is the suggested way to do it.

Thanks a lot!
I was able to make the racket embedding code work...
...but now I have another problem: When I try to call scheme_basic_env()
the program crashes with an access violation error (reading location 0x0
so it's probably due to a NULL pointer).
I cannot perform any further debugging b
