Subject: DateTimeInterface is not a usable interface?
From: ocramius@gmail.com (Marco Pivetta)

Hello,

I was looking at DateTimeInterface in order to provide my own
implementation of it, when I hit this:

http://3v4l.org/8GvgO

 > "Fatal error: DateTimeInterface can't be implemented by user classes in"

Is there any actual reason for this kind of limitation?
Can it be removed before going stable?

I also wasn't able to find any RFC information around it on
https://wiki.php.net/rfc#php_55 - is there any previous discussion around
this, or did it just sneak its way in?

Greets,

Marco Pivetta
