It’s difficult to get right
It is actually really easy. I wanted to rewrite my old rust coded that I did while I was learning it. But when I checked it after about year I have found that it was pretty decent.
Compiler really did help (actually more like clippy/rust-analyzer in that case).
I've been fined on German highways for going too fast. Memes like these are myths. It is based on fact that there is no default upper limit on highway. But there are speed-limit signs on German highways.
