To be fair, the 5.5 situation without pulling in ZO+ is NOT the same as 5.4
was. Today, right now, there exists at least one stable open source opcode
cache. 5.4 had none for many months after release. So I'm not sure if the
same pressures exist.

The discussion now is if we delay 5.5 to spend the time pulling it in core.
But either way (in core or not), ZO+ is open and working on 5.5 alpha. So
we could skip the core import, and just ship it today as gold, and it would
be adoptable straight away (unlike how 5.4 was).

That's the thing though, it wouldn't be a partial solution. It would be
exactly where 5.2, 5.3 and 5.4 are today, with the addition of several
highly wanted features.

I'd rather delay 5.6, and do a deeper integration into the engine. Then at
least there's something to gain by pulling it into core, rather than just
having it be a compile-time-flag as opposed to a pecl installation (which
doesn't buy us *that* much)...

My standpoint at least...

Anthony
