// Closure literal declared (and used) inside a `defer` body.
//
// Regression (issue 0073): this used to segfault lowering. A lambda inherited
// the enclosing function's `func_defer_base`, so the lambda's `return` re-drained
// the enclosing function's defers — and when the defer body itself declared the
// lambda, that re-lowered the lambda forever (infinite recursion). A lambda now
// opens its own defer window (like every other function-lowering entry).
