[FlashCodersNY] default parameter :Number

[Rich Shupe]

I would like to use null as null (for removing something from memory, for
example) and not let it be assumed to be "meaningless" (couldn't think of a
better word) as in this case.

I do use null as an argument for event listener functions, but that's not
relevant because the params don't have user-defined default values.

Maybe I'm just used to AS3 and I don't know that it's a sub-optimal way to
do it.

Related: I think your "equivalent (e.g., NaN)" choice was because this was a
Number data type, which is an important thing here. Different data types
have different default values in AS3. I found that tedious at first. (Not
being able to use undefined in every case, for example.)
