When Guido designed Python he made a clear separation between statements
and expressions. (You might want to contrast this with Lisp where there
is no difference between statements and expressions.) I find myself
occasionally rebelling against this, most usually when using lambda
expressions, where statements might come in handy. As I've gotten used
to Python, I've also gotten used to the "Pythonic" notion that the way
to handle these situations is to define a function and then invoke it.

Were you here for the great "if-then-else" operator war? Given all the
controversy associated with adding an if-then-else expression, I think
any proposal to add any form of try-except expression is certainly
doomed to failure.
