Bleh, C++ is so ugly. I can't see how D can't do better.
operator overloading works fine in D, just like it does in the given
What C++ allows is:
1. operator overloading of arbitrary operators. D has certain
requirements for certain operators.
2. extracting the operator overloading to a module-level function. D
requires operator overloading inside a type.
But neither of those problems are in play here. You could practically
port the solution exactly to D.
HOWEVER, I don't think the mechanics make this solution worthwhile.
Carrying around extra structs and wrapping things in this complicated
way doesn't seem very attractive to me.
