Ugly custom operator

dot.cpp

#include <iostream>

class DotOp {

};

class LhsDotOp {
	public:
	int value;
	explicit LhsDotOp(int value) : value(value) {}
};

// Of course you should have vector instead of int and the real operation instead of + ;)

LhsDotOp operator*(int value, DotOp) {
	return LhsDotOp(value);
}

int operator*(LhsDotOp lhs_dot_op, int value) {
	return lhs_dot_op.value + value;
}

#define DOT * DotOp() *

int main(int, char**) {
	std::cout << 42 DOT 34;
	return 0;
}
