Indeed.

Or add a pragma to tree "-0" as false in boolean context:
use feature "minus_zero_is_false";
print "Yes" if "-0";
would then not print anything.

boolean context is simply something you should not be doing for
similar reasons that you generally are not comparing floating point
numbers for equality.
