Where I live there are a lot of “temporary” 30km/h speed limits that were never removed by the road workers after the work was completed.

Just an arm and leave it with the battery, problem solved.

let statements only reserves space on the stack

It is not guaranteed to do that. It could also use a register or be optimized out completly (like in the example you posted in the other comment).

The stack pointer is also not changed for each local variable, but instead for each function call, so it wouldn’t make a difference anyway.

A slightly better metric to train it on would be chances of survival/years of life saved thanks to the transplant. However those also suffer from human bias due to the past decisions that influenced who got a transpant and thus what data we were able to gather.

And then Discord arrived

The comparison with Discord makes non sense, the feature seems to be just a normal group chat, like the ones in Telegram/Whatsapp/iMessage. Discord’s killer feature is the ability to have multiple channels within a server, which allows more organization.

Even in english this isn’t true, for example dots can appear inside a sentence for multiple reasons (a decimal number, an abbreviation, a quotation, three dots, etc, etc), which would make you split it into more than one piece.

I hate all the cruft in my home directory, but I also hate when stuff suddently stop working after an update, or when all the documentation online talks about something that doesn’t work on my system or is not there anymore. Developers are the ones that will have to deal with people with these issues, so I can see why they are reluctant to implement the naive solutions that some ask for.

What you need here is not the stability in memory (i.e. of pointers, which you lose when you recreate an object) but instead just the stability of an identifier (e.g. the index into a list).
