It's not a syntax change, but it is a very, very large engine change. Yes,
it does not touch the Zend engine itself, but it adds a large amount of new
code that is close to the engine. People doing engine changes will need to
modify it too (thus it is quasi part of the engine, even if it lives in a
separate directory). All existing core devs will have to study and
understand the code. All new developers have an additional piece of very
complex code to study before they can start making core changes.

So no, this is not a syntax change, but it is a engine change with a by
*far* larger impact than any of the other things that have been introduced
in PHP 5.5 (like generators or finally).

That's why I asked about the type of vote. I'm never quite sure which kind
of vote something requires (maybe we could clarify that paragraph in the
voting RFC a bit?)

Thanks, Nikita
