C++ TODO / FIXME macros that expire (fail to compile) at a given date

TODO_BEFORE() and FIXME_BEFORE() macros insert a compilation "time bomb" that will trigger a TODO or FIXME build error a soon as the given date is reached.

This is useful to force attention on a specific piece of code that should not been forgotten among a growing list of many other TODO or FIXME comments...

Example

#include "static_todo.h"

TODO_BEFORE(01, 2018, "refactor to use std::optional<> once we compile in C++17 mode");
bool readConfigInt(const std::string & key, int & value);

 In file included from example.cpp:1:0:
static_todo.hpp:48:5: error: static assertion failed: TODO: refactor to use std::optional<> once we compile in C++17 mode
     static_assert((year >= 2018 && month > 0 && month <= 12) &&                                    \
     ^
example.cpp:6:1: note: in expansion of macro 'TODO_BEFORE'
 TODO_BEFORE(01, 2018, "refactor to use std::optional<> once we compile in C++17 mode");
 ^~~~~~~~~~~

Supported compilers

The code requires a C++14 compiler (it won't work in C++11 mode).

It has been successfully tested with a high level of warnings on:

g++ >= 5.1 (-std=c++14)
clang++ >= 3.9 (-std=c++14)
VC++ 2017 (/std:c++14)
