Subject lines says it all, I think... The choice to make binary operators implementable only via this `opBinary` template means it's unclear how to get virtual operators on an interface.
I am very new to D, and my goal is to learn how to solve this problem using classic, runtime, dynamic polymorphism in D (so, please don't suggest that I solve a different problem, suggest that I use a particular library, a different technique, etc.). Thanks in advance.
As said virtual functions cannot be templates. However you can use alias to essentially define what you want your operators to be called.
I wrote a blog post on how to use a single mixin to forward all operators to the D1 style overloads. You might find it useful or inspiring.
