Add @comma directive or similar

[jkoop]

What do you guys think about adding this simple @comma directive?

For example, here's my code:

// app/Providers/AppServiceProvider.php

public function boot() {
    Blade::directive('comma', function () {
        return '<?php echo $loop->last ? "" : ", " ?>';
    });
}

{{-- .../uhh.blade.php --}}

@foreach ($campers as $camper)
    <a href="/camper/{{ $camper->id }}">{{ $camper->name }}</a>@comma
@endforeach

Looks good to me.
