Assignment operators definitely should return lvalues normally.

why deadalnix would think otherwise. It's pretty much the norm

see no reason for it to be different in D. No, it doesn't work 
for all types,
but in the general case, it should.

At least int assignment isn't lvalue. I find this quite 
surprising:

void edit(ref int) { }

void main()
{
    int n;
    //edit(n = 4); // Error
    edit(n += 4);
}
