Sez to meself, "What's he talking about ?". Checked out your link. Just
great ! One of the most elementary and *very useful* concepts in
programming has a name coined for it :-)

When I learned it, it was called a "Three way split". I like pictures better

Very nice. Your diagram cut right through it! Perhaps if the
instructors went back to calling it a "three way split" the students
would catch on more.
