That syntax looks a bit backwards to me. What if I want to 
annotate the attribute.

@serializable struct @foo {}

Looks a bit confusing which is the name of the attribute and 
the which is the attached annotation.

Vs

@serializable @attribute struct foo {}

No confusion here, "foo" is the name of the attribute, the rest 
is attached annotations.

I guess it depends. I find it easier to see that it's an 
attribute, especially when you annotate it. But it's harder to 
grep for.

Is foo an attribute or not?
  @serializable
  @xmlRoot
  @attribute
  @displayName("foo")
  struct foo {}

Is foo an attribute or not?
  @serializable
  @xmlRoot
  @displayName("foo")
  struct @foo {}
