           Summary: [task] Protocol: Make enums a type for arguments
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: john.kare.alsaker at gmail.com
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: wayland
           Product: Wayland

Enums should be their own type so could specify that you are passing an enum by
using type="enum.<enum name>". For the error event where any enum can be
passed, we could use type="enum". When the enum is specified in another
interface, we could use type="enum.<interface>.<enum name>". I'm not sure how
this should interact with multiple versions or how it currently does. We could
also just use type="enum" for these cases.

Adding enums as types serves as documentation and adds type safety for
generated code in languages which features such for enums. The effect on C
source and ABI should be none.
