I feel like the majority of the time you just have arrays or slices of a manageable size, say <= 25 elements, and you just want to delete an element from it. You don't care about performance because it'll be fast regardless and surely not the bottleneck of your program.

In my experience with Go, a lot of basic functionality is missing and requires you to write your own utility functions. And some things you would expect like mySlice.append(elem) are instead written mySlice = append(mySlice, elem) which isn't as elegant. Plus you have to remember it's not just append(mySlice, elem)

If there's a handful of open source utility function libraries, that will split the Go developer base, kind of like how you used to have both jQuery, Prototype.js, underscore.js and others in Javascript. They should have just standardized all the common functionality you'd want and in an intuitive way.
