That's not a literal, it's a display. The difference is that
a literal denotes the same object every time it is executed.
A display creates a new object every time it is executed.
(another difference is that a display is a constructed thing
which may contain runtime-computed components, unlike a
literal).
So if bytes are mutable and also have source-level
representation, they should be displays, not literals.
