While we're on the subject of assignment expression limitations, I've
occasionally wanted to write something like
try:
return a_dict[key]
except KeyError:
return (a_dict[key] := expression to construct value)
You can already do that with `return a_dict.setdefault(key,
your_expression_here)`. If the expression is expensive to evaluate you
can use a short-circuiting conditional expression to guard it.
