          Issue ID: 18780
           Summary: Inconsistent behavior with Variant holding int
                    converting to unsigned types
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: phobos
          Assignee: nobody@puremagic.com
          Reporter: alex.jercaianu@gmail.com

This code works fine:
     int x = 7;
     Variant a = x;
     assert(a.convertsTo!ulong);

This assert however triggers:
     int x = 7;
     Variant a = x;
     assert(a.convertsTo!uint);

Is this behavior intended?
