x/net/context deprecation proposal

// This program demonstrates that the standard library's `context` package
// is the correct import to use.  The deprecated `golang.org/x/net/context`
// package is no longer imported, so no deprecation warning is emitted.
// The program prints the concrete type of the background context value.
package main

import (
	"context"
	"fmt"
)

func main() {
	// Obtain the background context from the standard library.
	c := context.Background()
	// Print the concrete type of the context value.
	fmt.Printf("Context type: %T\n", c)
}
