arxiv.org is a thing

While you do have a fair point, I was referring to the case where one is basically implementing a map operation as a for loop.

Technically this is also possible with for loops, like with OpenMP

Compiler optimizations like function inlining are your friend.

Especially in functional languages, there are a lot of tricks a compiler can use to output more efficient code due to not needing to worry about possible side effects.

Also, in a lot of cases the performance difference does not matter.

We had one who pulled up the pdf of the textbook to read it word by word

I was garbage collector for 3 years as student job.

Not a single person in the company has done such a thing. We did dumb shit all the time but that wasn’t even close. I feel sorry that you decided that 1 person represents a whole industry

As long as you use proper lifting form it’s not that hard on your back. Without it you won’t last long though.

Also here in belgium all garbage collectors I know earn more than the teachers I know.

You get most of the day off after having worked a full day + still need a full and thorough shower + have low energy because it’s a physically demanding job

Src: did it for 3 years as student job

Fun fact: the main reason garbage collection is unhealthy is because you spend all day in the fumes of public roads & the truck you’re hanging behind.

Source: was garbage collector for 3 years as student job & we got a small hourly bonus for it.

Did it as a student job for 3 years. I was paid roughly 50% more than with all other student jobs.

Honestly collecting garbage is not even that bad. I got paid to do fitness all day, spending time outside while chatting with my coworker. The people sorting the trash, that was who we felt bad for. They had all the downsides of the job with none of the benefits.

Dogmatic statements like this lead to bad, messy code. I’m a firm believer that you should use whatever style fits the problem most.

Although I agree most code would be better if people followed this dogma, sometimes mutability is just more clean/idiomatic/efficient/…
