this, Scope Resolution, and Automatic Lifetime: Pitfalls

Pitfalls and red flags

• Writing name = name in constructors and leaving members uninitialized by shadowing.

• Assuming automatic methods make object fields thread-local during parallel calls.

• Using static members without class scope qualification and accidentally shadowing identifiers.

• Keeping temporary computation in object fields instead of locals, creating avoidable races.
