That would mean creating more keywords, which would break code.
By using @, we
avoid having to create new keywords, which I believe was the
whole point in
the first place. Which attributes got @ on them was fairly
arbitrary, but they
do definitely serve a purpose. And any new attributes in the
future will
probably have @ on them for the same reason.

Please don't.
This was the approach taken by Java with the @overload and
friends, which leads to ugly code in my opinion.
Once I worked in a project which took a similar approach, we
would have annotations as a way to extend the core grammar. Each
team eventually grew its own set of annotations, to the point the
amount of annotations became bigger than the core grammar itself,
with overlapping meaning.
