I actually am (either that or get what you want done in some other
way). It's a rare enough use case that I think it's a very reasonable
compromise. The disadvantages of adding a whole new branch of syntax,
for this rare use case, far outweigh its advantages - IMHO.
Rare use case? Have you seen any recent Java framework? Or Java EE 6? Or
design by contract in C#? A declarative programming style can be very
handy.
Besides that, did you look at the other languages annotation support
and how and why they are used?
I have but I think we've hashed this many times in the past - PHP is
PHP, not C# or Java. There's a serious cost in complexity with every
new feature we add - especially a complicated syntax-rich feature like
that - which I believe we all too often fail to factor into our
discussions.
The fact that PHP is not C# or Java doesn't mean we shouldn't look for
useful features in those languages, so it's not an argument. What you have
to say is why you think annotations, while possibly making sense in C# or
Java (depending on your position on that), do not make sense in PHP.
I also think you are overestimating the complexity introduced by this
feature. The patch is not particularly complex. We have doubtfully useful
features such as LSB which are more complex not only in implementation,
but also in usage.
I though adding support for this was more or less consensual, and it was
just a matter of tuning important but secondary details.
