I thought this was going to be a nested collections coding abuse link.

   new List< List< List<String> > >();

I can't think of use case for this.

    new List< List< List<String> > >();

seems a reasonable model of,

    new Table< Column< Row >> ();

You cannot think of a usecase for list of matrices or a usecase for 3-tensor?

A similarly amusing Wikipedia page is the one on recursive islands and lakes [0], where you can find such curiosities as a lake on an island in a lake on an island in a lake.

Sadly google's satellite resolution isn't high enough to see the final island of the worlds only 'island in a lake on an island in a lake on an island in a lake'.

I wonder how one would get there.

But notably, the current list of lists discussion is the only one containing a list to HN discussions.

Does that make this a supermetalist?

Curious that the lists regarding computers, software, and programming is so sparse given that 'software is eating the world'

  Lists of computers
    Lists of mobile computers
    Lists of microcomputers
  Lists of programming languages
  Lists of software
  Lists of websites

Another interesting one, in this regard, would be: https://en.wikipedia.org/wiki/-ism
