To be fair, this is not the entirety of C++ but C++ following the Google C++ Style Guide, which limits use to a more manageable subset of the language. For instance, exceptions, which can be especially hairy in a language with manual memory management, is prohibited. Take a look at the Fuchsia codebase. The code is really quite clean and readable.

Compared to the midnight bamboo forest my company built. A challenging codebase, not by its merits but because you need to be clever just to find your way through.
Anyone know if Google is hiring webforms developers?
