Statistics is another area where multiple return values could be of 
interest -- one may want the mean and std dev, and making two passes 
is wasteful (since some of the same info needs to be computed both 
times).

A do-all function that computes min, min location, max, max location, 
mean and std dev all at once would be nice (especially if the 
returned values were accessed by name, rather than just being a tuple 
of values, so they could be referenced safely and readably).
