I was thinking bout this analogy:
1. try/else (without except) is SyntaxError. And seems useless.
2. try/break/except is backward compatible:
for i in L:
try:
break
except Something:
pass
except break: # current code has not this so break is applied to for-block
3. for/raise/except (which is natural application of this analogy)
could reduce indentation but in my personal view that don't improve
readability (but I could be wrong)
It could help enhance "break" possibilities so "simplify" double break
in nested loops.
for
broken = False
for
if condition1(): # I like to "double break" here
raise SomeError()
if condition2():
break
except SomeError:
break
except break:
broken = True
4. for/finally may be useful
