    nested scope
       The ability to refer to a variable in an enclosing definition.  For
       instance, a function defined inside another function can refer to
-      variables in the outer function.  Note that nested scopes by default work
-      only for reference and not for assignment.  Local variables both read and
-      write in the innermost scope.  Likewise, global variables read and write
-      to the global namespace.  The :keyword:`nonlocal` allows writing to outer
-      scopes.
