In combination to the existing proposals we already voted one, this RFC
includes a fourth option that has not been discussed before,
and could be the compromise we are all looking for :-)

@[Attr] combines both the with to use the familiar @ of many, and the wish
to have a closing symbol/termination symbol that many others have.

It does not have the downsides that Tyson found w.r.t. to #[Attr] being
interpreted as comment on PHP 7, but that also means its not forward
compatible like #[Attr] is.

It provides a small BC break where code written as @[$foo, $bar] = baz();
or $foo = @["bar" => $baz]; will not compile on PHP 8 anymore, but that can
be easily
fixed by writing it with a space between @ and [.
