// EXPECTED_REACHABLE_NODES: 1277

// This test's purpose is not preventing regressions, but rather making sure the array-to-string conversion is tested at all.
// The `expected` values in asserts just reflect the current state of things. It doesn't mean things _must_ be this way.
// So feel free to update them if you're sure that the array-to-string conversion should behave differently.
