Can you (abstractly, briefly) describe a few of them?

(For me, `nil` is a _symbol_ for "there's nothing here", so the approach 
of actually storing nils seems backwards… and so I'm looking for other 
solutions.  Having a bunch of test problems would be handy.  I scanned 
through the relevant threads I recalled and didn't find any good ones.)
