I'd like to have a function (or other callable object) that returns
0, 1, 2, etc. on repeated calls. That is:
print f() # prints 0
print f() # prints 1
print f() # prints 2
# etc.
There should never be any possibility of any number getting returned
twice, or getting skipped over, even if f is being called from
multiple threads.
What's the simplest and most natural way to do this? I can think of a
few but am not sure that they work. And I can think of some ways that
are sure to work, but are messier than I'd like.
