Just because HHVM is closer to PHP than C#.

Why not like C#?

[Description("My Function")]
function my_function()
{}

Without the semicolon, this wouldn't be valid in any other context.

Hi!

No, but this is valid:

@atrr(); function foo() { ... }

That's perhaps a little too close for comfort...?
That's different syntax. If you put ; in the middle of statement, it can
change - "$c =3D $a + $b;" is not the same as "$c =3D $a; + $b;" - but
nobody thinks + can not be used because of that. As I said, << and >>
are existing operators too, so if you are creative enough, I'm sure you
can find cases like that too.

Hi Stas,

You may try to replace attribute syntax with @attr(...) (without semicolon)=
 into our PHP parser.
Note that we have LALR grammar + restrictions caused by semantic actions.
If you are able to do this, I'll add it into the RFC as an option.

Thanks. Dmitry.
