I agree.

We would benefit from explicitly including code reuse (user-defined
functions and modules) in P scope, I think. It makes P more complex
and more powerful/useful. If this is in the charter, then we would not
have to argue again whether the added complexity is worth the
benefits.

Please note that user-defined functions are NOT user-defined actions.
I know I was sloppy about this terminology in the past.

Agreed, at least for this iteration of the charter.
