Here's a quite balanced talk about FP and OO that fits my view of the two paradigms. Give it a shot if you have 40mins on your commute or something.

TIL: paste -sd+
Following https://hacker-tools.github.io/ lectures, I found a neat trick I didn't know in the data wrangling chapter:
seq 100 | paste -sd+ | bc -l # 5050
That's pretty nice. I already had this usecase solved by an "addup" perl script that I stole years ago from Mark Jason Dominus' utils repo.
As a bonus, it reminds me the very similar trick to generate a regex that matches either of many words. That's part of my git pre-commit hook
Not exactly the same, but it also belongs to "Higher Order Shell"
