6cd74b03f3 Don't use a named pointer type as a receiver type. The
current spec forbids it:
    The type specified by the type name is called ``receiver
    base type''.  The receiver base type must be a type
    declared in the current file, and it must not be a pointer
    type.

2d4f7ba0cd printf as we know and love it.
Plus print[ln] with the ability to print struct values.

Note for language mavens: if a "..." function passes its argument
to another "..." function, the argument is not wrapped again.  This
allows printf to call fprintf without extra manipulation. It's good
but needs to go in the spec.

This code works:
///
package main

import fmt "fmt"
import os "os"

type T struct { s string; a, b int }

func main() {
	P := fmt.Printer();
	P.printf("%s = %d with float value %.4f\n", "hi there", 7, 123.456);
	P.println("hi there", 7, 123.456);
	P.fprintf(os.Stdout, "%s = %d with float value %.4f\n", "hi there", 7, 123.456);
	P.println(T{"x", 7, 234}, "end of struct", 8, 9);
}
