As you describe, functions are special for your scenario because a
function definition needs to result in executable code as an object.

You answer this question.

Yes. The two facts are directly related.

What is the crisis (“a stark change from one state to another”) that
you're referring to by “a critical point”?
Yes, functions are different and are treated differently. What's your
