How may I start a racket command-line (or emacs subprocess) with the
at-exp racket language? (or at-exp something else) The obvious
racket -l 'at-exp racket'
doesn't work.

How are parameters implemented. My conceptial model is an association
list (like in the original Lisp 1.5 manuel) would suffice, but that can
lead to long searches.
What is actually done in Racket?

A parameter object itself is essentially just a key. To get its value, you
first look up the current parameterization in the current continuation's
continuation-marks. The parameterization contains an immutable eq?-hash
mapping parameter keys to thread cells. The parameter's value is the value

Yes. Racket was born in Texas, so it is an homage (not a political statement :)

When trying to u[dat catalog I get a message

should do the trick. For example, to start a REPL in typed/racket with
@-reader support, you would use:

Thanks. It works like a charm. But isn't a very nice recipe.
Are there reasons why -l 'at-exp racket' sdhouln't be made to
The -l option loads a module path. As `racket --help` documents, `-l ` is
equivalent to `-e '(require (lib ""))'`. Since (require (lib "at-exp
racket")) won’t help you much, neither will `-l 'at-exp racket'`. I’m not
totally sure why you thought `-l` was the right option here, but it doesn’t
I tried this but had no luck;
Miriams-MBP:~ spdegabrielle$ cat start.rkt
#lang at-exp racket/base
(require racket/format)
(displayln "try me")

@~a{foo bar}
Miriams-MBP:~ spdegabrielle$ racket -t ~/start.rkt -i
Welcome to Racket v7.6.
try me
"foo bar"
"foo bar"

That sounds like a great idea, though it's not our current aim. We do hope
to eventually build a benchmark suite for the community, and that may
enable improvement of profiling tools down the line.

A snapshot catalog only lasts for a limited time, and v7.4.0.1 was a
very long time ago in snapshot terms.
So, the short answer is to upgrade to a new snapshot --- or switch to a
release, which doesn't time out.

Hi!
For the first time, I published RN and forgot to send an email the list
