@soft youd think id get used to softism eventually, but no, it keeps surprising me
@vantiss at least the VAs sound like they're having a blast
Hi @vaporeon_, a while ago we talked about the fact that references were introduced to C++ in order to enable operator overloading. You asked why you have to introduce references to enable this and I said that you didn't and it was an unnecessary complication.
I've been thinking about this and I don't agree anymore.
In C++, operators used with class types are syntactic sugar for method calls:
#include <iostream>
class NumWrapper {
public:
int val;
NumWrapper(int n) : val(n) {}
NumWrapper operator+(NumWrapper& r) { return NumWrapper(this->val + r.val); }
};
int main() {
NumWrapper l(3);
NumWrapper r(4);
std::cout << (l + r).val << "\n";
std::cout << l.operator+(r).val << "\n";
}
So why not make the overload method take pointers instead?
class NumWrapper {
public:
int val;
NumWrapper(int n) : val(n) {}
// why didn't c++ implement operator overloads like this?
NumWrapper operator+(NumWrapper* r) { return NumWrapper(this->val + r->val); }
};
Well, imagine we used an rvalue as one of the + operands. Then a pointer to an rvalue would be passed to the overload function. rvalues normally have their addresses hidden from the programmer (you can't give them to &). Then operator overloading would circumvent this feature and allow the programmer to access the address of an rvalue.
I currently believe that references were introduced so that C++ could have a pointer-like language construct that does not expose the addresses of rvalues.
