my favorite example is the featureful yet short grep, supporting quite a few non-trivial options as well as a detailed '--help' message. :)

Does getOptions really take an arbitrary n-tuple? Why? That seems a very odd way of doing things. The only advantage I can think of over lists is that tuples don't have to be typically homogeneous, but I would have thought that you could get your ?? and ==> operators to spit out the correct types. -- -David House, dmhouse@gmail.com, http://xmouse.ithium.net
