(../include/grpc++/impl/codegen/config.h). Instead, pointers should
be checked for validity using their implicit conversion to `bool`.
In other words, use `if (p)` rather than `if (p != nullptr)`
+- Do not initialize global/static pointer variables to `nullptr`. Just let
+ the compiler implicitly initialize them to `nullptr` (which it will
+ definitely do). The reason is that `nullptr` is an actual object in
+ our implementation rather than just a constant pointer value, so
+ static/global constructors will be called in a potentially
+ undesirable sequence.
- Do not use `final` or `override` as these are not supported by some
compilers. Instead use `GRPC_FINAL` and `GRPC_OVERRIDE` . These
compile down to the traditional C++ forms for compilers that support
