Subject: Re: [PHP-DEV] A little syntactic sugar on array_* function calls?

While the argument No. 2. is completely valid, the 1st one is not so.
If you remove whitespaces around the `|>` and also if you alias these
functions to `map` and `filter` respectively (or if, for instance,
some future RFC moves them into a special `PHP\Array` namespace, which
would probably never happen, but it's allowed to dream), it could look
like this:

```php
$array|>map($fn1, ?)|>filter(?, $fn2);
$array->map($fn1)->filter($fn2);
```

A bit longer (due to 2.), but not that much, actually.

Best wishes,
