Spark helper functions

Spark helper functions.php

<?php

/**
 * @return \App\User|null
 */
function currentUser()
{
    return request()->user();
}

/**
 * @return \App\Team|null
 */
function currentTeam()
{
    if (!request()->user()) {
        return null;
    }

    return request()->user()->currentTeam();
}

Nice. Do you a global helper function for such helpers or do you use it in your base controller?
