// expected: closure captures outer variable(s) [recv]
//
// A bound method value holds its receiver, which is a capture: the closure
// would have to carry the operand. Legacy rejects it for that reason, so
// `defer c.Close()` is the only way to defer a method call - there the
// receiver travels as an argument on the defer record, not in an environment.
