digitalmars.D.bugs - [Issue 6936] New: type combination is not commutative


           Summary: type combination is not commutative
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: timon.gehr gmx.ch

Tested with DMD 2.056.

const(int[]) x;
const(int)[] y;

static assert(is(typeof(1?x:y) == typeof(1?y:x))); // fail.

Error: static assert  (is(const(int)[] == const(int[]))) is false

The static assertion should pass.

I suggest the common type in this case should be const(int)[]. That is
consistent with how type combination works for basic types.
