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.)


I like to think that t={} creates a table with every possible numeric, string, boolean etc key value pre-filled with nils. pairs() just ignores nil values.
