PEP 765: Disallow return/break/continue that exit a finally block

PEPs
23

Yes I agree with the re-raise analysis, but see no real difference in break/continue/return inside an except block or a finally I really would prefer the same behaviour. I can always use sys.exc_info to discover information about unhandled exceptions although that is a bit clunky.

I don’t find anything special about the exception suppression; after all except blocks can choose to suppress an exception by just not re-raising.

import sys
for i in range(3):
	try:
		raise (ValueError if i==2 else RuntimeError)(i)
	except ValueError:
		print('raised')
		continue
	finally:
		print(f'finalised {sys.exc_info()==(None,None,None)}')
		continue
else:
	print('else')

I’m sure there are many other gotchas in python which are not regarded as syntax errors mutable default arguments are often used wrongly (by me).

I think foot-shooting should be allowed :wink:
