Scribbling Documentation 4.1.4, Defining Racket Bindings, shows how to
access a module function and 4.1.5 documents evaluating examples.
I cannot get a function to be recognized. It 'turns' bright blue, but
has a red underline. What do I misunderstand?

I don't immediately find an *introduction* to Racket's automatic memory
management, in the Guide, Reference, or Quick manual.
Perhaps the Guide could say something briefly about this early on, for
the benefit of people coming directly from C or C++? As soon as they
start seeing values being a

hello Ted,
note that in most gc systems, you can't say "clean up X right now!"
which can be unfortunate when you are talking about trying to clean up
some X

Yes, that definitely does help. I was figuring this out and trying
to grok the docs and I also hit upon define-namespace-anchor which
seemed like it would do the job and does in fact look like it works
like I want it to. Good to hear I'm on the right track.
My eval definitely does contain at le
The GC finds objects that you cannot refer to and deletes them. All
other objects have some way of getting to them (chains of field
references), so they are not deleted. If you want to delete something,
you can't do it. You can, however, destroy references to it (set them
to #f, for example), so th
Thanks for this fast answer.
Unfortunatly, I'm familiar with this concept of garbage collector.
have I to send my instances to there or is it a way to get deleted data back?
Thanks.

Hi the list,
I'm a user of Fluxus http://www.pawfal.org/fluxus/
which is a scheme environnement for 3D, audio and games.
I'm trying to learn the racket Oriented Object style and asking myself a
thing?
How the objects can be deleted after their work?

Others will correct me if I have this wrong, but IIRC #:servlet-namespace is

Hello,
I'm using Racket 5.0.1 (from emacs) and I'm having trouble
understanding some behaviour I'm seeing in the web server.
