The term "attribute" is a bit confusing, especially since "property" is also used in the language to refer to something completely different. A better term is perhaps "annotation". The @foo is an annotation on x, but its type is just int. Furthermore, the @foo annotation on it only exists at compile-type; it doesn't exist at runtime. The purpose is really to enhance compile-time introspection and metaprogramming; but what the OP wants seems to be something else altogether. Sadly, the "attribute" terminology has stuck, and is unlikely to change. T -- What do you get if you drop a piano down a mineshaft? A flat minor.
