In cases where None is a valid result, you can't use it to signal failure.
Asked and answered. You change the "sentinel" in .fetch to something
else.
When did I specify a sentinel value? You're saying that if None is a
valid value in the dict, you can't use slice syntax for it.
But y'all keep on defending the language making your programming
decisions for you!
Your example is the one where the language makes programming decisions
for you. Your language is deciding that if I use slice syntax, I want
the sentinel to be None. Python is deciding that unless I give it a
sentinel, there is no sentinel.
