I would parse those differently, but you may be right that they'll always have the same final result.
I'd like to get some certainty on this. I'm not aware of any value of 'a' for which #10 and #11 give different values. Can you (or anyone else) think of any such value?
Technically they should result in different code, though.
Maybe. We need to think. Should can be a difficult word. Elsewhere you have, as I recall, pointed out that if None: do_something() generates no code.
Perhaps the compiler should collapse #11 to #10, if they are equivalent. But this is a side issue.
So, are there any values of 'a' for which #10 and #11 don't give the same result?
I'm not prepared to put my neck out and say "They are absolutely identical" and have people jump on me with some technicality. What is your point here? ChrisA
