From reading forum posts I managed to figure out that
HexStrings are prefixed with an x. i.e. x"deadbeef"
Good catch! Even the grammar says nothing about what it is,
except it has HexString as a possible literal.
Can you file an issue? https://issues.dlang.org

They are deprecated:
https://dlang.org/changelog/pending.html#hexstrings
https://dlang.org/deprecate.html#Hexstring%20literals
Hence, the grammar has been incompletely updated. As it's not an
error to use them now, it should have stated that they are
deprecated.
Anyhow, you can always go back in time:
