Someone correct me if I'm wrong, but I think that's true only if you use methods and not operators, because Go doesn't support operator overloading.

The other place you really feel the lack of generics is in the collections. They are built around the empty interface so that they can hold any type. Then you have to cast back to what you want. Exactly like Java pre generics. ugh.

That's correct, which means stonemetal's comment is true only for non-math code, but 99% of the code out there is not math.
