You have no idea how many times I had to fix script errors like this one.

My favorite is how you can compile functions with array arguments defaulted to none with no problem, but you can't compile anything that uses that function's argument default, making it useless.

And what about a function defined like:

Actor[] Function IAmEmpty(String SomeParam)

 return None

EndFunction

And then you try:

Actor[] myActors = IAmEmpty()

And the papyrus log tells you that an array cannot be cast to None.

Papyrus inforces coding style, y'see

int y = omg + 1
int omg = 1
