Not exactly what you want, because it logs the filename and the line number, but here is how I do it in my Tideland Common Go Library (http://tideland-cgl.googlecode.com/) using the "runtime" package:

// Debug prints a debug information to the log with file and line.
func Debug(format string, a ...interface{}) {
    _, file, line, _ := runtime.Caller(1)
    info := fmt.Sprintf(format, a...)

    log.Printf("[cgl] debug %s:%d %v", file, line, info)
