Apparently I was too specific and pragmatic.
Let me try the opposite: Maybe more general than you want. :)
After spending some years with Racket, I've noticed certain things are
very popular targets of extension or customization. One is `define`.
Another is `struct`.
The catch is, these various

Thank you very much friend Paulo. I think you are right. Maybe really it is
an experiment. Eventually, if you have some news about, please let me know
at fbenn...@libero.it.
Thank you again and a nice day for you.

Great, thanks. I clearly need to add the section on contracts to my
re-read list. I thought I understood them, but apparently there are still
bits that I'm missing.

Just spitballing here, trying to start with "what's the simplest
possible thing that could work?":
You could let the user flag a field as the event. I don't know your
surface syntax, but maybe using an `#:as-evt` keyword would be OK?
You could link/refer the user to the `prop:evt` docs, or, copyp
Your intuition is right, but let me make it more precise: foo? is used when
something is a flat contract, and foo/c is used otherwise. Flat contracts only
check first order properties of values, which is a technical term that captures
what you mean by “general nature.”
The important distinction
Your intuition is right, but let me make it more precise: foo? is used when
something is a flat contract, and foo/c is used otherwise. Flat contracts only
check first order properties of values, which is a technical term that captures
what you mean by “general nature.”
The important distinction
Is the idea that foo/c is used only when it will specify structure (e.g.
(hash/c any/c symbol?)) whereas foo? is used to check that a thing has a
general nature?

I use Racket yes, but I use chez scheme too. Anyway they are different. I
want to use both. If I do not put #lang
Off topic. ~~ It is ironic how 23 years after we started out and had an option
for DrRacket, née DrScheme, to run its programs in Chez instead Mz .. and now
we’re getting back to that :)

I am talking without running it or even having used that plugin but it
looks like it's passing the definitions you have in your window but Chez
doesn't know `#l` in line one. I imagine you have something like `#lang
racket`?
Why not just use Racket then? Also, are you sure you want to run Chez

Hello Paulo, thank you for your help. I have the button "Run Chez". I've
already installed it. When I press the button I get this error: Exception

This would probably sound like rambling but that's only because I am

Hi,
It seems you are referring to this DrRacket plugin:
https://github.com/Syntacticlosure/chez-runner
Optimally Syntacticlosure should be able to help a lot more than I can
and if what I say doesn't make sense, I suggest you open an issue with
your question at :
https://github.com/Syntacticlosur
Someone knows home to use the "chez-runner" plugin? I've installed it but
do not works.
