Hi Theodore,

Yes, in other context they are operators; the same that << and >>, the bitw=
ise shift operators, and the current syntax is already using them with a di=
fferent meaning.

The ones I put in my original message were just examples of tokens we could=
 use, maybe =93&=94 can=92t be used because it can conflict with references=
, but there are some others I think can be used. Let=92s bringing them all =
together:

// From my original message:
*Deprecated
%Deprecated
>Deprecated
function foo() { }

// New ones:
:Deprecated
=3DDeprecated
function foo() { }

We are looking at what other languages are doing, but currently PHP =93supp=
orts=94 (not natively) *attributes in docblock comments, and it=92s a fairl=
y used feature:

/**
* @Deprecated
*/
function foo() {}

The closest usable token with one and two symbols would be * and *@ respect=
ively. Anyhow @@ seems faster to type than *@.


Anyway, what I was trying to expose is that, as we can not directly adopt s=
yntax for another language, maybe it would be better to not introduce a 2 c=
hars token with BC breaks, and maybe go with a even shorter token with no B=
C breaks.

Which token? I think there are a lot of them we can use, and for sure anyon=
e has its preference; and that=92s why I was also suggesting to pick a few =
of them, vote them in the RFC, and go with the winner.

Regards,
Iv=E1n Arias.
