> I agree with your concerns regarding debuggers and crash dumps, though in my experience you need debuggers far less often when writing Rust code, and when you do need them (e.g. for unsafe code) you've often already used `repr(C)` on the types of interest.

I disagree with the "it's already repr(C)" bit. While for Stylo most of my debugger usage has been on C++ or FFI code, when working on Servo proper I've had to debug plenty of pure Rust Servo code, and have rarely dipped into repr(C) code.

I do agree that with Rust I've had to use a debugger less often overall.
