This brings up a question I have (hope it's okay to divert the topic
slightly). Should I write a common piece of code as a callable function,
or should I just make it some script that I can include (seems like it
would save the function call). If I write a function, I have to include
the file where I keep the function, anyway. So I tend to simply include
the "function" inline and then document the include file with pseudo
inputs and outputs (what vars does it depend on and what vars does it
change).

Integrity is obvious.
