The author explains surprising behaviors of Rust's borrow-checker through interactive examples, including evaluation order in assignments, two-phase borrow activation in method calls, reborrowing mechanics, and explicit drop semantics. The analysis suggests many Rust developers lack understanding of these edge cases despite using the language regularly.
