Defining an opAssign for S seems to do the trick:

int test()
{
    struct S { int x; void opAssign(S s) { x = s.x; } }
    S t1;
    S* n1 = new S;
    *n1 = t1;

    return 10;
}
pragma(msg, test());

This also works:

(*n1).tupleof = t1.tupleof

The compiler can do it... it's just that this expression doesn't work.

Workaround #2:
int test2()
{
    struct S { int x;  }
    S t1;
    S* n1 = &(new S[1])[0];
    *n1 = t1;

    return 10;
}
pragma(msg, test2());

Something gets weird when using `new S` - it seems the allocated block is marked in some way that prevents *m1 = t1 from working.

I also thought of and found that workaround... it's fine for arrays. It's very strange that because it's just one, this doesn't work.

It seems this can be fixed by teaching assignToLvalue about StructLiteralExps:


        else if (auto sle = e1.isStructLiteralExp())
        {
            oldval = sle;
        }

There may be issues with this fix though.
