- for value types, ``h`` pads the value to 32 bytes in the same way as when storing the value in memory. - for value types, ``h`` pads the value to 32 bytes in the same way as when storing the value in memory.
- for strings and byte arrays, ``h`` computes the ``keccak256`` hash of the unpadded data. - for strings and byte arrays, ``h(k)`` is just the unpadded data.
