Potential feature?

I wonder if this reflection tool could be a useful addition to PlutoTeachingTools ? It allows checking functions, entered into a cell by a notebook's user, for required or undesirable function calls.

I am using it, for example, to automate checking for usage of a previously defined method in programming assignments, because students frequently cut and paste code, rather than call a function they just wrote.

It looks very useful! I think it needs a bit of work to make the documentation and API easier to use. Maybe we need to find a good name for this, and give some easy examples.
