That's great to see. It's sometimes hard to keep up with everything that's going on. Incidentally I really got a kick out of the recent s/Uint/UInt/ rename (https://github.com/JuliaLang/julia/issues/8905). It took a day or so to propose and do it. To compare, java will probably never fix it's spelling oddities (for example int and Integer). Very refreshing to see fundamental things like that be fixed and so quickly!
Just to play devil's advocate about the Java capitalization, I suspect the difference between `int` and `Integer` is quite intentional: `int` is a "primitive", immutable value type, while `Integer` is a class. Since by convention, Java's classes are capitalized, while its primitives are spelled the way they are in C, there's some sense here.
