they discourage the use of templates and frown on
metaprogramming, among
other shocking things (like prohibiting exceptions, using
2-space
indentation, and other "interesting" things [1]).
The Google cppcon presentation was pretty clear on this, e.g.:
1. The code should be easy to understand at the call site for a
non-expert. No need to look up the docs. They don't care if code
is tedious to write, because reading is more important and
frequent.
2. Exceptions hide error_handling, so they have their own status
class that force error-handling or explicit "ignore()" to make
code review easier. C++ exceptions also come with a performance
penalty.
3. No non-const ref parameters to functions, use pointers. They
want a visible "&" at call site for output parameters. e.g.
"read(&var)" so that you don't have to look the function up in
the docs.
4. They use clang with C++11 and standard libraries.
5. Formatting debates are not interesting. Use automatic clang
formatting, it is better than most programmers anyway.
