          Issue ID: 15601
           Summary: version not allowed within enum declaration
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: epi at atari8.info

The following declaration is not accepted. Compiler complains "Error: basic
type expected, not version".
It can be worked around by versioning the entire enum declaration (code
duplication) or string mixin (ugly).
