Victor:
Python.3 Type System [IHN] - The use of “extended precision” as a term to
express Python’s ability to create and manipulate integers of any size (within
the memory limitations of the computer) is poor since that term is used in
reference to floating point numbers almost exclusively. I will change it to
“unlimited precision” in the revised annex.
Python.16 Wrap‐around Error [XYY] - My source for this is in the Python
documentation under the 2nd reference to OverflowError in:
http://docs.python.org/py3k/library/exceptions.html?highlight=overflowerror
Python.23 Initialization of Variables [LAV] – Point taken on the unusual syntax
(I am not a Python programmer) and I will change to the more common syntax s
per
your 2nd suggested syntax.
Python.32 Structured Programming [EWD] – The point I was trying to make was
that, unlike many early languages, Python has no constructs, like the ones
mentioned, that can be used to create an unstructured program. I am not
advocating, nor would it be proper in this kind of paper, that the Python
language be extended to allow for unstructured statements. I will try to
clarify
this better in the revised version.
Python.51 Undefined Behaviour [EWF] #1 – I need to do more research as your
example does suggest that mutating, at least, does raise an exception. Here
are
a few references that claim that this is undefined:
Refer to (10) under:
http://docs.python.org/release/2.4/lib/typesseq-mutable.html
Python.51 Undefined Behaviour [EWF] #2 – In regard to collections.OrderedDict,
since I am only listing undefined behaviors I don’t think adding a defined
behaviour here is appropriate.
Python.52 Implementation–defined Behaviour [FAB] – In regard to mixing tabs and
spaces, I will add your advice to the 52.2 Guidance section
Thanks for your excellent comments; the paper will be improved because of them.
