Yes. > And I need to name it for each type differently? Yes. > Why? Because Go does not have generics. There has been a enormous amount of discussion on this in the past that I won't try to summarize here. You could read https://golang.org/issue/15292. > All I want to be able to do is to find an item in a Slice. > > Why does "append" work with all types then? Because it's easy to write a short correct find loop for the type you are using, but a good implementation of append is a much larger function. See also http://www.airs.com/blog/archives/559 .
