How to Use Weak Pointers in Go 1.24

Go 1.24 introduces weak pointers via the new weak package, allowing references that don't prevent garbage collection of target objects. Unlike strong references, weak pointers become nil once the object is collected. This feature is useful for temporary caches, observer patterns, canonicalization, and preventing reference cycles in dependency graphs. Developers must check for nil values when using weak pointers, as objects may be collected during any garbage collection cycle, and the Value() method must be used to access objects safely.
