Larry's suggestion about #[Attr] makes an important argument about allowing
to declare attributes in code in PHP 7 in a forward compatible way that has
not been brought up before.

/** @ORM\Entity */
#[ORM\Entity]
class User {}

This code would work on PHP 7 and 8.

The #[] syntax would have about equally low breaking potential as @@. It
would be the same syntax as Rusts, and close to C++/C# syntax.

As such, instead of going through each alternative syntax one by one, with
with each having a 2/3 requirement to overthrow the old one,
I would be open to restart the secondary vote on Attributes syntax with
<<>> (status quo), @@ and #[] using the same ranked voting algorithm that
was used for the PHP 8 RM vote.

@Sara @Gabriel I suppose this is something you two should be ok with (and
Theodore of course).

I would take on the work to write about the third syntax alternative then.
The VoteRFC could just link to the three individual RFCs where each
discusses their syntax.
