That "signed string" is a unary minus expression using an absolute value forced
by the inadequacy
of the literal representation syntax.
IOW, IMO '-' + hex_literal_of(abs(x)) is not a decent hex_literal_of(-x) !!
This has been discussed over and over, but since you bring it up again:
There are no hex literals for negative numbers, just as there are no
decimal literals for negative number. A literal, by nature, in any
base, is non-negative.
If you disagree: Is 0xFFF6 a positive or a negative number?
