OK thanks for this, the easily mock thing is indeed very nice to have. And maybe Generics will improve things. I don't get why there isn't a function to remove element from a slice (there's some append[:i],[i+1] trick instead) why wouldn't this be wrapped in a stdlib function? call it delete or something. I keep hearing good things about the stdlib - what am I missing? It's that do it yourself mentality I really don't like, and taking huge compromises on readability to preserve low language keyword count (like the lack of private keyword / capitalization the article discussed and the consequences) and then calling this whole setup "simple". There's nothing major but many many small things I think that make it a subpar experience. I don't care that much about performance and concurrency though which I think are Go's strong suits.

Rails. A bit of Django and Node. All 3 were better in my eyes but as I said in another comment I care very little about performance and concurrency so maybe I'm not Go's target audience.
