           Summary: typeof(x~y) should never be const(T)[]
           Product: D
           Version: D2
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: timon.gehr gmx.ch



typeof(x~y) should never be const(T)[].
const only has a meaning in presence of aliasing. Unique const data is
meaningless.

int[] a;
immutable int[] b;
const int[] c;
static assert(typeof(a~b)==int[]);
static assert(typeof(a~c)==int[]);
static assert(typeof(b~b)==immutable(int)[]);
static assert(typeof(b~c)==immutable(int)[]);
static assert(typeof(c~c)==int[]);

(of course, this only applies if T has no mutable indirections)
