I love how Rust has so many footguns that you need to read a dozen blogs from no less than a month ago to avoid utter confusion.
Some might criticise it for forcing you through a complex process to acquire a firearms license, selling you gun with an efficient safety and then insisting that you wear extremely heavily armoured shoes.
So to use the foot gun analogy, if you don't know the stuff in the article you wont even be able to pull the trigger.
An actual footgun is something like monkeypatching in python or ruby. Or running for_each with an async callback in javascript.
