That sums it all up for me as well, though I would rather use "else" instead of "or?" (see punctuation-heavy). `else` is ambiguous. Consider:
result = spam if eggs else cheese else aardvark
could be interpreted three ways:
result = (spam if eggs else cheese) else aardvark result = spam if (eggs else cheese) else aardvark result = spam if eggs else (cheese else aardvark)
Whichever precedence you pick, some people will get it wrong and it will silently do the wrong thing and lead to hard-to-diagnose bugs. Using "else" for this will be a bug-magnet.
I wouldn't make a mountain out of a molehill. Other existing operators have the same issue.
Which other keywords or symbols may be either a binary operator or part of a ternary operator depending on context?
