// expected: init() is not allowed in main package
//
// A main package's setup belongs in main(), which is the program entry; an
// init() there would run before it with no defined place in the entry
// sequence. Legacy says so, and stage4 now rejects it too: it used to print
// "init() is not allowed" and skip the function, so the program built and the
// init never ran - a silent difference, not a rejection.
//
// A library package may have exactly one init(), which runs after its
// package-level variable initializers and before any importer's.
//
// Note on legacy: its package-declaration checks are gated on the shape of the
// package path, so legacy rejects this file when the build root resolves to a
// module path but accepts the same source copied to a bare out-of-tree
// directory (whose path has no dot). stage4 applies the rule by package kind,
// which is what the rule says; the restriction harness copies test sources to
// an out-of-tree directory, so this one is intentionally stage4-only.
