I agree: it is unfortunate that the original language designers used the
term "global" to mean "persistent global". Had they separated the
concept of scope from the concept of variable duration/lifetime, the
language would have been equally powerful while being easier to understand.
What is a non-persistent global?
In any language I've worked with, you declare a global and it stays in
memory until you delete it or quit the program.
I don't know of any language that deletes globals automatically based on
whether the app closes or opens files from disk.
