the end of the containing function. To fix that, the runtime provides
a special hook that lets us obtain a defer "token" representing the
outer function and then use it in a later defer to attach the deferred
code to that outer function.

Normally,

	defer print("A")

compiles to

	runtime.deferproc(func() { print("A") })

This changes in a range-over-func. For example:

// that suggests a 'go get' command for root packages that transitively import
// packages from modules with missing sums. load.CheckPackageErrors would be
// a good place to consolidate errors, but we'll need to attach the import
// stack here.
type ImportMissingSumError struct {
	importPath                string
	found                     bool
	mods                      []module.Version

// orig must be an *Alias, *Named, or *Signature type. If there is no error,
// the resulting Type is an instantiated type of the same kind (*Alias, *Named
// or *Signature, respectively).
//
// Methods attached to a *Named type are also instantiated, and associated with
// a new *Func that has the same position as the original method, but nil function
// scope.

that can be used in TLS handshakes, controlled by the [`tlsmaxrsasize` setting](/pkg/crypto/tls#Conn.Handshake).
The default is tlsmaxrsasize=8192, limiting RSA to 8192-bit keys. To avoid
denial of service attacks, this setting and default was backported to Go
1.19.13, Go 1.20.8, and Go 1.21.1.

Go 1.22 made it an error for a request or response read by a net/http
client or server to have an empty Content-Length header.
