+Static arrays are exactly like c arrays, difference is
+we can easily then get a slice of that array.
+
+Slices are static arrays + length, they simplify array handling.
+This allows us to pass an array into a function easily, then that function
+can still access that length information easily.
+
+Passing a pointer to array + length is a common pattern in C. So it would
+be nice if handling of that was simplified.
