/**
* @def Y_ARRAY_SIZE
*
* This macro is needed to get number of elements in a statically allocated fixed size array. The
* expression is a compile-time constant and therefore can be used in compile time computations.
*
* @code
* enum ENumbers {
* EN_ONE,
* EN_TWO,
* EN_SIZE
* }
*
* const char* NAMES[] = {
* "one",
* "two"
* }
*
* static_assert(Y_ARRAY_SIZE(NAMES) == EN_SIZE, "you should define `NAME` for each enumeration");
* @endcode
*
* This macro also catches type errors. If you see a compiler error like "warning: division by zero
* is undefined" when using `Y_ARRAY_SIZE` then you are probably giving it a pointer.
*
* Since all of our code is expected to work on a 64 bit platform where pointers are 8 bytes we may
* falsefully accept pointers to types of sizes that are divisors of 8 (1, 2, 4 and 8).
