More generically speaking, shells typically use dynamic scoping rather
than lexical scoping, which means a variable only persists until the
scope where it is declared finishes, and while it persists it is
available to all deeper scopes.  The zsh/param/private module changes
some of the availability rules, but nothing changes the persistence.
