Indeed! You could then even have arrays of ErrorVal objects with no 
extra effort, at least as long as ErrorVal doesn't implement the 
sequence protocol (because then all the Numeric functions will silently 
convert them to arrays).

Your module looks interesting. What does it do internally, interval 
arithmetic?
