You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: version.go
    path of file: ./repos/goa/pkg
    
    the code of the file until where you have to start completion: package goa

import (
	"fmt"
	"regexp"
	"strconv"
)

const (
	// Major version number
	Major = 3
	// Minor version number
	Minor = 15
	// Build number
	Build = 1
	// Suffix - set to empty string in release tag commits.
	Suffix = ""
)


    
func Compatible(v string) (bool, error) {
	matches := versionFormat.FindStringSubmatch(v)
	if len(matches) != 4 {
		return false, fmt.Errorf("invalid version string format %#v, %+v", v, matches)
	}
	mj, err := strconv.Atoi(matches[1])
	if err != nil {
		return false, fmt.Errorf("invalid major version number %#v, must be number, %v", matches[1], err)
	}
	return mj == Major, nil
}
