Interesting Custom Function behavior

Well, I just spent at least half an hour beating my head against the wall over what turned out to be a very silly error, but it led to an interesting discovery.

I was editing a script that I knew was working, but when I went to save changes, it gave me an Invalid Parameter error. So I canceled the edit, went back in, and tried it again. Same thing. After considerable futzing around with the script, I decided to actually re-create the script, and made an interesting discovery.

If you create a custom function with multiple parameters, incorporate it in a script, then edit the function and change the number of parameters, the function keeps working in the script, even with the invalid syntax. Apparently there's no dependency checking when editing custom functions.

While I wouldn't call it a bug, this is definitely unusual behavior.
