the handiness of undef becoming NaN (when you want that)

[David Nicol]

I am implementing a textbook algo in Perl (the textbook has
it written in C++) and have realized that if undef was to
numericize to NaN instead of 0, there are a lot of uninitialization
errors that would get caught.  

        use strict vars;

does not recognize use of new array indices as unitialized variables.
