Hi, First, thanks for your ideas. One downside with Henry's idea is that the attack function cannot access potential struct attributes of the Pitbull or Dog struct (I believe, correct me if I'm wrong). Although there weren't in my example, our code will certainly have struct attributes that need to be accessed during the «attack» portion of the code.
So I'd say that goes with Henry's vision, where there isn't a one-size fits all approach to those problems. I think we'll stick with the type-independent function for now as it looks like the most versatile - Julien On Tuesday, 31 January 2017 07:34:29 UTC-5, Henry wrote: > > Hi, > > One thing that I learn about Go is that it forces you to look for a > specific solution to your problem, and the same solution usually cannot be > applied to other similar problems.
