From: francois@tekwire.net (=?utf-8?Q?Fran=C3=A7ois_Laupretre?=)

Hi Dmitri,

Yes, unfortunately, PHP features not compatible with the PHP 5 =
interpreter will be harder to adopt for most developers, even if they =
are not technically BC breaks.

I agree with your POV, as I now  think that it shouldn't be included in =
the core, provided we have the needed hooks. I explain the hooks we need =
in the draft RFC. Can you tell me if it seems possible to you ?

>I see your point, and, of course, it makes sense, but it also means =
that no new PHP7 features might not be used in these >frameworks and =
libraries for a long time. Should we stop add new features in major =
releases?
>As I said, according to DbC, I'm not sure if it should be defined on =
language level. Doc comments or annotations with external >tools might =
be good enough.
