// expected: closure captures outer variable(s)
//
// A Moxie closure is a standalone function: it receives what it needs through
// its parameters and has no environment carrying outer locals. Legacy rejects
// a capturing closure in restrict.go; stage4 accepted one, so a program that
// only stage4 compiled could tie a closure's lifetime to a dead frame arena.
