          Issue ID: 13752
           Summary: add traits to query storage class of variables (isTLS,
                    isGlobal)
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: DMD
          Assignee: nobody at puremagic.com
          Reporter: code at dawg.eu

Knowing whether a variable is thread-local (TLS) sometimes allows to leave-out
otherwise necessary synchronization.
Currently it's extremely hacky to infer this, so a isTLS trait would be
helpful.
It might also make sense to add the complements isGlobal and isLocal.
