PSA: Most modern gyms have "autobelay" devices that let you climb on your own without a partner. This makes gym climbing a super fun and accessible exercise anyone, even beginners, can do by just showing up to a gym at your convenience.
(If you're a beginner you should still take the 1 hour class first and you will have to pass a belay test. And yes, if you can make the schedule work out with a friend so can belay each other, that's even more fun)
You still need to be careful. I'm an avid climber. Most autobelay accidents happen because people don't clip in properly. However for me the auto belay cable broke after catching me. Resulted in five minor spinal fractures.
So from my experience I would say at least Google what are the common auto belay manufacturers and only use gyms that have them. True Blue and Perfect Decent are the only auto belays I will touch now.

This is really cool, does it fix OpenSCAD's need to spam epsilons everywhere to avoid Z-fighting?
TBH I am not sure but I suspect the answer is yes. I use OpenCascade as the base CAD kernel and it handles things like Z-fighting a lot better. I built DSLCAD after completing porting OpenSCAD to wasm because I wanted a better programmatic CAD platform. It's development is really "as I need it" from then on.

For those who are interested. I have been working on a similar CAD Modeler. I think of it as a spiritual successor to OpenSCAD.
It has support for bidirectional modeling (ex: get the height and width of an object and use it later) and multi part workflows to design more complex works.

They should also correlate navigational ability with IQ.
If such a correlation exists or doesn’t exist says a lot about navigation.
An informal test:
Are there any really smart people here with credentials and credibility to prove it who are also complete garbage at navigation?
My partner is a medical doctor. She can't navigate around. I don't think there is any link. Navigation was something that I was taught early and is a skill like anything else.
There is something nice and pure about this site. It is probably just coincidence and random that the number 37 is seen around. Likely something along the lines of the Baader-Meinhof phenomenon.
However none of that matters. What matters is the site is there for all of us to enjoy. It made me smile and I appreciate that.

Good write-up. What was understated but I appreciate was that this optimization was done late and after being picked up via profiling. For devs there is sometimes a drive to do this kind of work early. It really should always be done late just as in this post.
Would writing out text files be an option?
I've been trying to do this from OpenSCAD (now using RapCAD) and while I sort of have it working:

I'm not so far along that I wouldn't try something else.
You have a super interesting use case. Can you reach out on the github issues so that we can track it? From what I can tell you are trying to generate GCode directly from the software is that the case?
Chamfer and fillet are awesome, but the pipe… mixed feelings, especially since it uses a dash. Either a normal pipe or an Ocaml-like |> would feel more natural.
The goal of pipe is to allow the code to read top to bottom. I always found it hard to explain the way an OpenSCAD program reads upwards when nesting operations.
As for the syntax there are certainly a lot of ways it could feel. JS devs would likely be familiar with =>, F# and Ocaml |>, Java ->. In the end I just picked one that felt natural to type for myself. From my experience if you write in enough languages you develop the ability to switch as needed.
I don't live in the states so it's not as dramatic legally as you may imagine.
