           Summary: std.traits.hasElaborateAssign is limited
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: rejects-valid
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: nobody puremagic.com
        ReportedBy: k.hara.pg gmail.com



Follwing code should compile:

struct S
{
  void opAssign(T)(auto ref T rhs)
    if (!__traits(isRef, rhs))
  {}
}
static assert(hasElaborateAssign!S);

Because hasElaborateAssign!T checks is(typeof(T.init.opAssign(T.init))),
but T.init is always lvalue, so S cannot pass its test.
