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: wsl.go
    path of file: ./repos/steampipe/pkg/utils
    
    the code of the file until where you have to start completion: package utils

import (
	"log"
	"os"
	"runtime"
	"strings"
)

// cache for the WSL value, so that we don't have to query the OS all the time
var isWsl *bool = nil

// IsWSL detects whether app is running in WSL environment
// refer to: https://github.com/Microsoft/WSL/issues/423#issuecomment-679190758
func IsWSL() bool {
	if isWsl != nil {
		return *isWsl
	}
	if runtime.GOOS != "linux" {
		w := false
		isWsl = &w
		return false
	}
	// https://github.com/Microsoft/WSL/issues/2299#issuecomment-361366982
	osReleaseContent, err := os.ReadFile("/proc/version")
	if err != nil {
		log.Prin
    
func IsWSL() bool {

	}
	// https://github.com/Microsoft/WSL/issues/2299#issuecomment-361366982
	osReleaseContent, err := os.ReadFile("/proc/version")
	if err != nil {
		log.Println("[TRACE] could not read /proc/version for evaluating WSL: ", err)
		// WSL systems will always have the /proc/version file.
		// if we can't read the file, then this must be some other
		// flavour of linux which doesn't use it - or there's something
		// fundamentally wrong with the installation.

		// in both cases - assume this is not WSL
		return false
