ah, that makes sense! but what about something like ConvertFromTo(F,T) ? i mean, we need a single method func convert(f F) T but where should it go

but where should it go (which type should implement it)?
- ori_b 7y agoThe issue there has nothing to do with generics. You need overloading for what you want (and, IMO, overloading is a bad idea). Don't write code that way. Since conversion is rarely a generic pattern anyways, you just pass a conversion function in. func processStuff(type U, V)(a U, b V, convert func(U) V){ bleh(a, convert(b)) } processStuff(123, "foo", strconv.Itoa) Adding the parts needed to do generic conversion functions is not a great idea. That way lies madness and SFINAE.
