Please read my other, detailed post on this (8/5/2005 4:05pm). It is a
mistake to bypass control flow exceptions like GeneratorExit and
StopIteration. Those need to remain under Exception. Focus on your
core use case of eliminating the common idiom:
try:
block()
except KeyboardInterrupt:
raise
except:
pass # or some handler/logger
In real code, I've never seen the above idiom used with StopIteration.
Read Guido's note and my note. There are plenty of valid use cases for
a bare except intending to catch almost everything including programming
errors from NameError to StopIteration. It is a consenting-adults
construct. Your proposal breaks a major use case for it (preventing
your sales demos from crashing in front of your customers, writing
fault-tolerant programs, etc.)
