I think we pretty much all agree on that. However, you did see the note
about the difficulty of using default parameters in built-in functions,
right?

I ultimately ended up with 4 constructors, each with the same name but
0, 1, 2, and 3 parameters. Suggestions welcome.

There are a few ways to handle that. I would lean toward parsing the
NULL as a special keyword, and then rejecting it (does it matter if it's
upper case?).
