/*

# static_assert

Make assertions at compile time.

In this way you don't waste time compiling large programs,

or do potentially dangerous runtime operations to test your program.

Probably became possible on C++11 because of features such as `constexpr`,

which allow to better manage compile time constantness.

// ERROR: needs to be a constexpr

//static_assert(std::rand() >= 0);
