It may gives them less headache but if the part about the antivirus flagging the exécutable as suspicious it may give the users headaches..

I still find weird that they didn't make A,B... just after the digits, that would make binary to hexadecimal conversion more efficient..

I worked (a long time ago) on a C project where every int was wrapped in a struct. And a friend told me about a C++ project where every index is a uint8, uint16, and they have to manage many different type of objects leading to lots of bugs.. So it isn't really linked to the language.

I've seen some issue with this approach is that management will want to sell the prototype, bypassing the "rewrite from the lesson learned" step, and then every shortcut took into the prototype will bite you, a lot..

And things like "race conditions"/lack of scalability due to improper threading architecture aren't especially easy to fix(!)..

It's a minor detail but list starting at 1, with -1 being the last élément and 0 being 'none' is weird.. Why did you make this choice instead of 0 for the first élément, -1 for the last one? It would avoid the 0 'trap'.

> Eventually both Windows and Linux programs moved to a model where the OS just gave you the window as a drawing surface, and you were supposed to fill it.

If you follow this model, how do you solve the accessibility issue?

>signed integer overflow being UB would count for C/C++

Then, I raise you to Zig which has unsigned integer overflow being UB.

Not true, there's int and Integer.

It depends a lot on what you do on your holiday. I think it's best to start with something "mind focussing": you're not going to think about your job while skydiving, scuba-diving etc.

For && and || I disagree: they are 'shortcircuiting' operators and as such they deserve a différent name than just 'and', 'or'. That said &| should have been named and,or which would have freed &| to use for the shortcircuit operators.

So you're using proof on every line of code you produce?

Once Claude found a bug in my code but I had to explain the structure of the data. Then and only then it found the bug.

Of 'yourself', if a text field contain embedded/nested text you need to escape the delimiter.

Error safe, the : or :: I kind of doubt it, I think that finding a typing mistake (two : instead of 1) won't be easy..

Your point is funny but if you're not anal-retentive about the syntax you get monstrosity such as the CSV-escape rule instead of the passwd-escape rule..

> Dual use means extra ceremony with escaping

It depends, if you allow nesting you also need escaping.

I wonder if it wouldn't be better to have two fans: one at a high position and one at a low position.

No, it doesn't. But I'm not sure that this matter, a sufficiently "smart" compiler understand that this is the same thing.

Sure, but remember that some wipers were "hand activated".
