EnumSetType derive on newtype?

[eikesr]

I expected this to work. Am I doing something wrong?

#[derive(EnumSetType)]                                              
pub struct MyAwesomeEnum(foo::my_enum);

Unfortunately, since custom derives work on the syntax level, there'd be no way to make this work, unless EnumSetType is already derived on foo::my_enum (in which case, why not use it directly?). #[derive(EnumSetType)] needs to read the actual definition of the enum to properly implement the trait.
