If the struct is from some 3rd party source, how can I add such
an operator overloading to it? Is it possible to "extend" a
struct later?
Oh I see what you mean now. In JavaScript you can for instance
extend Array with an user defined method like;
Array.prototype.insert = function(index) {
...
return this;
};
Of course in d CTFE helps for similar cases. But I am afraid
operator overloading outside struct/class body is not available
in D. It would be nice feature though.
