For the latter: the documentation apparently wasn't fully updated in
r19260: it only changed ref7.tex, but not ref6.tex. IOW, it really
means to say "in the try clause", and it is out-of-date in saying so.
As for "continue in the 'finally' clause: What would that mean?
Given
def f():
raise Exception
while 1:
try:
f()
finally:
g()
continue
then what should be the meaning of "continue" here? The finally
block *eventually* needs to re-raise the exception. When should
that happen?
So I would say: It's very easy to fix, just change the message to
SyntaxError: 'continue' not allowed inside 'finally' clause
:-)
