No, I don't suggest it, but criticize it. Rust performs its checking as a separate step after actual compilation, which sometimes leads to strange behavior (like borrow errors are shown only after actual compilation errors). I prefer an approach which is integrated with other language mechanisms.

It's generally a good idea to write such an analyzer, but I doubt it can be useful without proper integration with the language itself (with huge semantics changes). If it's too strict, it will reject perfectly fine code, but otherwise it will catch only the most obvious errors and approve code having more complex memory bugs.
