Kris,



I=E2=80=99ll make it short.



EVERY RFC affects the language in *some* way =E2=80=93 be it its features,
positioning, perception, performance, implementation, testability, you name
it.  Each and every one, or we wouldn=E2=80=99t be discussing it on php.net=
=E2=80=99s
internals@ mailing list.  So I=E2=80=99m afraid I=E2=80=99m not going to us=
e *your*
interpretation for what the Voting RFC means (which in effect is either 2/3
majority for every RFC) =E2=80=93 but rather, what I *know* is the meaning,=
 and
what is clearly the spirit of the RFC.  Spirit I say?  Here=E2=80=99s what =
I mean:



*=E2=80=9C**Given that changes to languages (as opposed to changes to apps =
or even
frameworks) are for the most part irreversible=E2=80=9D*



Implementation improvements such as PHPNG are not irreversible.  New
features or changed features are.  This deals with language features, that
once we publish, we cannot take back as people already start using them.



*=E2=80=9Cthe purpose of the vote is to ensure that there's strong support =
for the
proposed feature.=E2=80=9D*



Is PHPNG a feature?  No, it=E2=80=99s not.  It=E2=80=99s improvements & per=
formance
optimizations at the implementation level.  Those who have been following
my involvement on internals@ over the years know my position about both
feature creep and downwards compatibility, and I=E2=80=99m absolutely certa=
in that
it was clear to them =E2=80=93 most if not all =E2=80=93 what the meaning h=
ere was.  That=E2=80=99s
100.0% irrelevant to PHPNG.


FYI, I don=E2=80=99t intend to ping pong with you about it.  I=E2=80=99ve s=
aid what I had
to say about that topic.



Zeev
