Byte Values
Byte values have the type Byte, which corresponds to an unsigned 8-bit
integer ranging from 0 to 255. It is generally recommended to use Int8
instead of Byte when performing math operations, however, Bytes are used in
API methods for Text and Path that deal with raw binary data, such as
Path.read_bytes() and Text.utf8(). Byte literals can be written using
the Byte() constructor: Byte(5).
