Can I add a couple of questions ...

What would happen if you had a go at doing the questions yourself rather than
	posting to the net?

What would happen if people posted only to *relevant* newsgroups?
(in this case comp.lang.functional and possibly comp.lang.ada)

PS. If you can convince me this is not homework I'll appologise and have a go
	at answering the questions, otherwise do your own work!
