 Hex strings are the most efficient way to embed binary data into source files.
 However, they couldn't easily be used to initialize a `short[]`, `int[]` or `long[]` because re-interpret casting arrays is not allowed during CTFE.
-Now, hex strings can be cast to integer arrays with element types larger than `byte`.
+Now, hex strings implicitly convert to all integer arrays.
 A big endian byte order is assumed, consistent with how integer literals are written.
