Which is the most important operator?
-------------------------------------
Personally, I think '?.' is the most valuable.
For me, it's the most contentious. The fact that a single '?' added to
a regular line of Python code can short-circuit execution silently is a
net detriment to readability, IMHO.
The only time it would short-circuit is when it would otherwise raise
AttributeError for trying to access an attribute from None, which is
also going to short-circuit. The difference is that it short-circuits
the expression only, and not all statements up until the next except
handler.
Cheers,
Steve
