[RFC] [VOTE] Shorter Attribute Syntax View as Markdown

I've opened voting on the Shorter Attribute Syntax RFC:
https://wiki.php.net/rfc/shorter_attribute_syntax

Since all RFCs require a primary vote with a 2/3 majority, there is
a main vote to approve the secondary ranked-choice vote.

For the ranked-choice poll, fill in your first through third syntax
choices, making sure not to select the same syntax more than once.
You don't have to vote for all three options, but please don't leave
gaps.

Voting will end in two weeks, on 2020-07-01.

I don’t understand this question:

Are you okay with re-voting on the attribute syntax for PHP 8.0?

Is this a vote to see if we want to re-vote on the attribute syntax? I
think this is worded awkwardly, and I’m not sure what the outcome of a
yes or not vote means for this question.

If I vote “no,” should I still vote in the secondary vote, or is
voting “no” effectively the same as choosing <<>> for all three
choices in the secondary vote?

Or, if I vote “no,” does that mean anything I select for the secondary
vote is thrown out?

You should vote in all four polls. If you choose "no" in the first one,
you might still have a preference for the syntax in case the outcome is
a "yes".

For your syntax preference, you can't pick the same option more than
once. This is ranked voting.

cheers,
Derick

I don’t understand this question:

Are you okay with re-voting on the attribute syntax for PHP 8.0?

I recommended this as a front-line question so as to remove any hint of
impropriety about the vote. For example, where the first round of the
secondary vote sits right now (15/15/4) we only have 44% in favor of any
specific change. That doesn't nearly meet the 2/3rd requirement. By
having a "pre-vote" to agree on reselecting the syntax, we have a CLEAR
2/3rd majority saying, "Yes, let's revisit this specific question again".

With that clarified, making the decision on what specific syntax we want is
less contentious. I had hoped that we wouldn't have a party split on the
primary vote, that people who wanted <<>> would still favor a
reconfirmation of the syntax since it was specifically cited that this
would be a point to come back to, but atm that's how things turned out.

Is this a vote to see if we want to re-vote on the attribute syntax? I

Yeah, the wording is awkward, but so is the situation. /shrug
I hope the above clarifies it.

If I vote “no,” should I still vote in the secondary vote, or is voting
“no” effectively the same as choosing <<>> for all three choices in
the secondary vote?

On the primary, you should vote yes if you believe it's worth revisiting
the topic, or no if you feel the people have spoken and alligator syntax
means alligator syntax.
Regardless of primary vote: You should vote on the secondary according to
your preference of syntaxes.

If @@ wins, will a sequence of 3-or-more @ characters forbidden?
It is not stated in the RFC. I.e. what happens if you write:

@@@ExampleAttribute()
class Foo
{
}

@@@some_function();

Hi Aleksander,

Yes, those examples would be syntax errors if the @@ proposal is
accepted.

Theodore

Hi internals,

The Shorter Attribute Syntax RFC vote is now closed. The primary poll
for re-voting on attribute syntax was approved with 50 in favor and 8
opposed.

For the secondary ranked-choice poll there are 61 valid ballots. Since
only one syntax can be elected, the quota is floor(61 / 2) + 1 = 31.

Note: one ballot wasn't counted since it selected the same syntax
more than once. However, this does not change the vote outcome.

In the first round the tally is as follows:

@@: 34 votes
#[]: 21 votes
<<>>: 6 votes

So @@ reaches the quota and has been elected as the final attribute
syntax for PHP 8.

Thank you to everyone who voted!

Hi Theodore,

Unfortunately, the RFC failed to mention a small, but important detail: The
@@ syntax is ambiguous, as pointed out by Martin Schröder:

function (@@X \ Y $param) { }

Taking into account that PHP allows whitespace between namespace
separators, this can either be interpreted as an attribute "X\Y" on an
untyped parameter, or as an attribute "X" on a "\Y" typed parameter.

The RFC implementation solves this by treating @@ and the following name as
a single token that does not permit whitespace. As such, it will be
interpreted as "X" with an "\Y" typed parameter.

Now, if this had been explicitly mentioned in the RFC, we could have made
an explicit decision to accept this language inconsistency: To forbid
whitespace in namespaced names for attributes only, unlike all other places
in PHP accepting namespaced names. However, it was not mentioned in the
RFC, and apart from the authors of the proposal, I don't think anyone was
aware of this ambiguity.

Fortunately, there is still a way to resolve this issue in a consistent
manner: Change the handling of namespaced names in PHP in general. This is
exactly what is proposed in
https://wiki.php.net/rfc/namespaced_names_as_token. If that proposal is
accepted, then the ambiguity would disappear (and the above example would
become a parse error).

My plan would be to change the
https://wiki.php.net/rfc/namespaced_names_as_token proposal to either only
deal with the handling of namespaced names (i.e. as a single,
whitespace-free token), or at least separate the other reserved keyword
related changes into a separate vote.

If that proposal passes, then there should be no issue with adopting the @@
syntax for attributes (unless there are other problems I'm not aware of?)
If it does not pass, then we'll have to discuss what we want to do here.

Regards,
Nikita
