/**
 * array_size - routine for safely deriving the size of a visible array.
 *
 * This provides a simple ARRAY_SIZE() macro, which (given a good compiler)
 * will also break compile if you try to use it on a pointer.
 *
 * This can ensure your code is robust to changes, without needing a gratuitous
 * macro or constant.
 *
 * Example:
 *	// Outputs "Initialized 32 values\n"
 *	#include <ccan/array_size/array_size.h>
 *	#include <stdlib.h>
 *	#include <stdio.h>
 *
 *	// We currently use 32 random values.
 *	static unsigned int vals[32];
 *
 *	int main(void)
 *	{
 *		unsigned int i;
 *		for (i = 0; i < ARRAY_SIZE(vals); i++)
 *			vals[i] = random();
 *		printf("Initialized %u values\n", i);
 *		return 0;
 *	}
