using `@attribute("...")` is ugly, but it has the advantage of simple 
workarounding for compilers that still not supporting that attribute. 
plus, it allows things like `@attribute("...") { ... }` or `@attribute
("..."):` on module level, whereas `pragma` isn't.

as for uglyness... it's too late to thing about this. one more, one 
less... ;-)
