I actually thought about it more, and D does have a bunch of 
binary operators that no ones uses. You can make all sorts of 
weird operators like +*, *~, +++, ---, *--, /++, ~~, ~-, -~, 
 >>>--, &++, ^^+, in++, |-, %~, ect...

void main(string[] args){
	test a;
	test b;
	a +* b;
}
struct test{
	private struct testAlpha{
		test payload;
	}
	testAlpha opUnary(string s : "*")(){
		return testAlpha(this);
	}
	void opBinary(string op : "+")(test rhs){
		writeln("+");
	}
	void opBinary(string op : "+")(testAlpha rhs){
		writeln("+*");
	}
}
