You've missed out a huge sector of programming languages; I'd be more inclined to take your claim of "unique" seriously if you'd included e.g. Haskell or OCaml.

More importantly, it's a massively biased comparison to look at a language from 3 years ago and compare it to those from 20, 30 or 40 years ago. Of course the standard library will be cruftier in an older language. The Idris standard library is beautiful, really state of the art - as you'd expect from a language that's only been written in the last couple of years.

It will be interesting to see what the Go standard library looks like in 20 years' time; I'm betting it will fare less well than Java's, because the workarounds and cruft necessary to avoid breaking changes will be worse in a language without Java's type system. In the meantime, the fair and informative comparison to make is with languages of a similar vintage.
