six characters to type vs 1 ?

  You can argue that either way. Seeing 'this' unambiguously implies instance variable. Otherwise you have to spot the underscore and be aware of the conventions in the codebase. A good IDE should highlight class variables vs locals, though. On the other hand code can get really messy with boilerplate like this everywhere, and I personally agree with you. Although I believe Google also promotes human-readable variables over less typing.

    I actually think implicit "this" is a language wart. I think C++, C#, Java, Swift, etc.. would all be better languages if they required `this`. As it is, nearly every one of them ends up needing a per team naming convention to help make the code readable. int area(int width) { return width * height; } What is "height". Is it a global variable? variable in some outer scope? A member/property of the current object? Absolutely no idea.
