I am emphasizing a point that I and others have made many times: in Python, we need to know exactly why an exception occurs.
Yes, we often see code like:
try:
...
except:
pass
…but we can fix that.
If ?. is used multiple times in a single line, it becomes a debugging nightmare. We cannot restrict users to only using ?. for optional data—they will use it simply because it’s trendy.
I see it becoming similar to the assert statement, which is almost always used in production—so much so that proposals to remove the -O and -OO optimization flags are frequently heard.
Or, removing indentation, so we could write code like this: def func(args): {print()}; def func2: {print()}, in a hieroglyphic style, etc.
