Mitchell Nordine has a very diplomatic way of describing the borrow-checker.
Rust tells me at compile time why what I'm trying to do is probably not a wise choice.
The complete quote:
I've found that Rust has forced me to learn many of the things that I was slowly learning as "good practise" in C/C++ before I could even compile my code. Rather than learning by trying to solve segfaults, debugging my pointer messes, etc, Rust tells me at compile time why what I'm trying to do is probably not a wise choice.
