// expected: package globals are immutable outside init
//
// A package global may only be written by init()/__varinit. stage4's check
// walked package members, so a store inside a function literal was never
// visited: the same assignment compiled cleanly when wrapped in a closure.
// Legacy rejects both, because the rule is a property of the store, not of
// where the enclosing declaration happens to sit.
