Emmanuel Gil Peyrot bcd42a26e3 macros: Use a nicer syntax when declaring attributes.
The previous version had a => required|optional|default token, this was
duplicating information for Option types and didn’t look very good.

This new version looks like a type, which can be either Required<_>,
Option<_> or Default<_>, and means the same thing.
