[TINSTAAFL][1], but what a functional programming paradigm takes away it replaces with brevity, concision, additional type safety, and greater opportunities for the compiler to restate your algorithms in a form more conducive to parallelization and concurrency.

    public function getTotal($tax)
    {
        $total = 0.00;
        
        $callback =
            function ($quantity, $product) use ($tax, &$total)
            {
                $pricePerItem = constant(__CLASS__ . "::PRICE_" .
                    strtoupper($product));
                $total += ($pricePerItem * $quantity) * ($tax + 1.0);
            };
        
        array_walk($this->products, $callback);
        return round($total, 2);
    }

Exile means to be away from one's home (i.e. city, state or country), while either being explicitly refused permission to return and/or being threatened with imprisonment or death upon return.

So he's probably not so much worried about whether or not he can return to the U.S., but rather what would happen to him when he did.
