Mike Innes is one of the real rockstars in the Julia community. He has a knack for making surprisingly small and elegant packages which compose so naturally with the base language that they feel built-in. After a `using Flux`, julia is suddenly a machine learning language, instead of a language with a machine learning library. I'd argue it shouldn't be surprising that he found his way to Julia because Julia is one of few languages that allows one to make such packages. His other packages such as MacroTools.jl, Lazy.jl and Zygote.jl are also well worth checking out.
