Subject: Re: [PHP-DEV] Introducing "Array Of" RFC
From: narf@devilix.net (Andrey Andreev)

--001a11c1236ab04d8d04f06e05e9
Content-Type: text/plain; charset=UTF-8

Please excuse my lack of knowledge, but if I understand this correctly,
this is how generics would work ... using arrays, ignore the syntax and
details such as child classes, interfaces, etc.:

   $fruits = Array<Fruit>; - declare that $fruits is an array that can only
contain instances of class Fruit
   function eat(Array<Fruit> $apples) - function eat() will only accept
arrays that are declared in the same way as $fruits above

If that is so, then I deffinately see how this RFC is similar to generics
and how generics would give us higher performance. But I also see how it is
different and how it serves for another (yet indeed similar) purpose.

I wouldn't rule out either feature, but if that is what you people want,
why don't you vote on:

    a) array of; b) generics; c) both

and be done with it. I surely do understand why Phil Sturgeon got so heated
about the discussion going nowhere - at least 3 separate topics are being
discussed here and everybody has an opinion on all of them separately. This
isn't productive.
