Kotlin null check for multiple nullable var's

Language Design

You can make a Util function that take array of values and check if they all not null
also added !! operator, but the operator only will leads for a null crashes if null appears.

    fun test(): Boolean {
        if(isNotNull(var1, var2, var3, var4)) {
            return procceed(var1!!, var2!!, var3!!, var3!!)
        }
        return false;
    }

    private fun isNotNull(vararg objArr: Any?) : Boolean {
        for(obj in objArr) {
            if(obj == null)
                return false
        }
        return  true;
    }
