identity

func Same ¶

func Same(a, b any) bool

Same reports whether a and b demonstrably name the same object.

Interface equality is not an identity primitive: it panics when a caller's concrete component contains a slice, map, or function. Comparable values can answer directly. Maps have stable runtime identity despite not being comparable as interface values. Everything else is conservatively different; an ownership boundary may repeat a focus transition, but it must never retain a gesture or a lease merely because two values happen to have equal-looking storage.
