The racket ppa for ubuntu has been upgraded to 5.1.1. This should work on
lucid (10.04)
maverick (10.10)
natty (11.04)
although I only tested on lucid. Thanks to Todd O'Bryan for poking me.

You probably want something like parameters.
You could make a language with dynamic scope if you really wanted it
though. You would capture variable accesses with #%top and friends. Or
you could just redefine binding/setting forms to use
parameters/globals+fluid-let.

Is it possible to declare a variable with dynamic scope?
Or is there a way of implementing this? Possibly using macros?

FrTime doesn't have a very good automated test suite, so it hard to
instantly fix problems. Mostly we check that the demos run before
releases. One of my goals is to improve its state (in particular, the
documentation) and see about making the implementation faster.

Anybody used something like this before? Sounds like an interesting

my use case is for substutition, and so need to work with regex-replace, as

information about Racket supporting this, am I wrong?

Hi all,
I have a small question about regexp-match:
when I want to insert a sub-expression followed by a number what should I
write?
like "\1001" to insert sub-expression 1 followed by 001
right now tries to insert sub-expression 1001... is there a way to
escape this?
thanks!

At first I thought you meant users would need to set this parameter

Hello José,
there is no direct link between the CLR and the Racket
runtime. Therefore you have two options:

I conclude differently, especially as LaTeX is a fairly horrible place
