Shall I do one where we count pixels? Because @@ is using a lot more of 
them... And there is also no reason why it can't be just:

    @[AttrWithParam("foobar")]
    @[SomeOtherAttr("fizzbuzz")]

Although group is allowed, it doesn't mean it's always useful to do.

    @@Attr1 @@Attr2 

Seems to me like a cat had trespassed on your keyboard, the *heavy* @@ 
also dominates the line.

From the RFC:
- No ending delimiter
- Doesn't allow grouping
- No forwards compat with PHP 7
- Not used ny another language

And the "familiar with docblocks" is quite a stretch, as that doesn't 
use @@ either. I've only included it because it would be unfair if @@ 
had nothing positive going for it.

cheers,
