Arithmetic operands can do unsigned work and have signed result. 

It is a quirk of the $signed() system function that the argument
is converted to signed, but the operation that is performed is
not changed. So arithmetic operators on unsigned arguments inside
a $signed() expression still perform unsigned arithmetic.
