Ah, I misinterpreted one of the examples, I thought that this would
work as you expect:
() { private foo; () { typeset -g foo=bar } }
(while this wouldn't:
() { private foo; () { foo=bar } }
)

But in both cases it is an error (although only the latter prints a
message and aborts execution), and foo is not set globally.

In fact a typeset -g is needed on the global level before the function
using private is called, which seems impossible for the innermost
function to enforce.
