State-Changed-Why:
This is not a bug.  The operator called is the one that takes a bool.  This
happens because the unqualified lookup only finds the second one you
define, and argument-dependent lookup looks in std and ns.  This worked in
2.95.3 because the standard library was in the global namespace, rather
than std.
