           Summary: TypeInfo_Ak and similar do not inherit from
                    TypeInfo_Array
           Product: D
           Version: 1.036
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: dhasenan gmail.com


TypeInfo_Array is never derived and is only used for struct and char arrays (as
far as I could tell). So you can't check if a type is an array type by casting
the typeinfo to TypeInfo_Array.

The following types represent arrays and should inherit from TypeInfo_Array:
TypeInfo_AC
TypeInfo_Ar
TypeInfo_Aq
TypeInfo_Ad
TypeInfo_Af
TypeInfo_Ag
TypeInfo_Ai
TypeInfo_Al
TypeInfo_Ae
TypeInfo_As

The remainder of the specifically-defined array types inherit from these.

Failing example:

void main ()
{
    auto s = "hello"d;
    auto sd = s[];
    if (cast(TypeInfo_Array)typeid(typeof(sd)) !is null)
    {
        assert (false, "not array");
    }
}
