There's one difference I think.
struct approach:
struct Area { int x, y; }
Area sqare(int a) { return Area(x, y); }
//foo and bar are attributed the same
@Area(5, 5) int foo();
@square(5) int bar();

whereas with the function approach:
@area(5, 5) int foo();
@square(5) int bar();
foo and bar have different attributes.

The problem is you can't define forwarding functions because the symbol 
is the attribute type. This seems to be a major problem to me.
