Hello everybody,
not sure if this is the good place to ask about this but I couldn't
find a good location so I'm asking for help here, after all it's
strongly connected to Racket :)
I'm trying to reverse-engineer some specific piece of hardware with
the help of Rosette, to discover if it can help

They sure do. Generally as 4x4 or implicit homogeneous 4x3 matrices to help

I'm just adding noise, but I just wanted to thank you for sharing your
plans, it's much appreciated, even when we don't answer in general.
Yep, told you so. Noise :)

Hello and thank you Ben for the explanation,
I had already implemented the workaround, I'll keep it :)
It seems that wrapping every binding access in a function is seen as
unnecessary in Scheme and Common Lisp ("Reference needed" :) ) but
it's a tool I use a lot in my favorite statically typed lan
Hello everybody,
I'm trying to gradually type my script to make it a proper app (yes
I'm a static-ish guy) and I have an issue (Racket 7.6 CS).

(provide (struct-out s))

Hello everybody,
I'm trying to drive a WIN32 application from a Racket gui app to provide
the QA guys a simple way to interact with it. So far I'm quite successful
but I'm having a little issue.
I spawn my subprocess with subprocess :
