          Issue ID: 20097
           Summary: SysTime cannot be used with std.concurrency.send
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: phobos
          Assignee: nobody at puremagic.com
          Reporter: chalucha at gmail.com

I've found that with Issue 6642 SysTime has been fixed to emit false to
hasUnsharedAliasing!SysTime.

So with hasLocalAliasing where is hasUnsharedAliasing used to determine local
aliasing it should behave the same.

Problem is again with a special case for Rebindable.

I'll try to make a PR shortly.
