[Tutor] Generator function question?

[John Clark]

Ooops - sorry - I spoke too soon...

It's clear that your code is a more elegant implementation of
neverEndingStatus() but I am still having to initialize a global variable
and call .next() when I want to get the next value... So the generator
function has been cleaned up, but the client code interaction with the
function is still pretty much the same.

(Either that, or I am not following what you mean when you say:

Can you please provide an example of how my Test1() function changes based
on your suggestion?  (sorry to be dense)

Thanks,
