Sorry, enter key added the issue when I was typing the summary.
Operator overloads require template functions, yet this doesn't work:
interface I
{
I addAssign(I other);
I opOpAssign(string op)(I other) if (op == "+=")
{
return this.addAssign(other);
}
}
void foo(I i)
{
i += i;
}
error message:
testinterface.d(4): Error: function
testinterface.I.opOpAssign!("+=").opOpAssign template member functions are not
allowed in interface I
testinterface.d(12): Error: template instance testinterface.I.opOpAssign!("+=")
error instantiating
How shall I implement operators for interfaces?

That should be op == "+". With that change I am getting the same error message.
Assigning to Walter to expedite review.

Any news on this? This is still very much a blocker for many designs.
