##### Byte string literals

A _byte string literal_ is a sequence of ASCII characters and _escapes_
enclosed within two `U+0022` (double-quote) characters, with the exception of
`U+0022` itself, which must be _escaped_ by a preceding `U+005C` character
(`\`), or a _raw byte string literal_. It is equivalent to a `&'static [u8]`
borrowed array of unsigned 8-bit integers.
A non-raw _byte string literal_ is a sequence of ASCII characters and _escapes_,
preceded by the characters `U+0062` (`b`) and `U+0022` (double-quote), and
followed by the character `U+0022`. If the character `U+0022` is present within
the literal, it must be _escaped_ by a preceding `U+005C` (`\`) character.
Alternatively, a byte string literal can be a _raw byte string literal_, defined
below. A byte string literal is equivalent to a `&'static [u8]` borrowed array
of unsigned 8-bit integers.

Some additional _escapes_ are available in either byte or non-raw byte string
literals. An escape starts with a `U+005C` (`\`) and continues with one of the
