* nail down a couple examples to have more predictable output
* update a number of things, but this is really just a stash...
* added an applications section to describe typical uses for native and machine-independent formats
* make sure all format strings use a format prefix character
* responding to comments from @gpshead. Not likely finished yet.
* This got more involved than I expected...
* respond to several PR comments
* a lot of wordsmithing
* try and be more consistent in use of ``x`` vs ``'x'``
* expand examples a bit
* update the "see also" to be more up-to-date
* original examples relied on import * so present all examples as if
* reformat based on @gpshead comment (missed before)
* responding to comments
* missed this
* one more suggested edit
* wordsmithing
* The struct module now requires contiguous buffers.
* Convert most functions and methods of the _struct module to Argument Clinic
* Use "Py_buffer" type for the "buffer" argument. Argument Clinic is
responsible to create and release the Py_buffer object.
* Use "PyStructObject *" type for self to avoid explicit conversions.
* Add an unit test on the _struct.Struct.unpack_from() method to test passing
arguments as keywords.
* Rephrase docstrings.
* Rename "fmt" argument to "format" in docstrings and the documentation.
As a side effect, functions and methods which used METH_VARARGS calling
convention like struct.pack() now use the METH_FASTCALL calling convention
which avoids the creation of temporary tuple to pass positional arguments and
so is faster. For example, struct.pack("i", 1) becomes 1.56x faster (-36%)::
$ ./python -m perf timeit \
-s 'import struct; pack=struct.pack' 'pack("i", 1)' \
--compare-to=../default-ref/python
Median +- std dev: 119 ns +- 1 ns -> 76.8 ns +- 0.4 ns: 1.56x faster (-36%)
Significant (t=295.91)
Patch co-written with Serhiy Storchaka.
* Replace "bytes" by "bytes object" in struct error messages
* Document the API change in What's new in Python 3.2
* Fix test_wave
* Remove also ugly implicit conversions in test_struct

Issue #7355: Various improvements to struct module documentation.
- note early on that the result of struct.pack includes padding
bytes by default
- add examples showing how order of struct fields can affect size
(due to padding)
- better headers and references; introduction to format strings
- integrate packing notes into table
Many thanks to Meador Inge for the patch.
