Shed-skin

-run shedskin itself with python 3.8..3.11 (but still only compiling python2-compatible code)
-add sunfish example
-move to c++17, allowing us to use std::hash instead of implementing our own algorithm
-optimize 'name in (expr, expr, ..)'
-optimize 'for i, c in enumerate(str)'
-add option to disable gc (-c/--nogc)
-add support for gc.enable/disable/collect
-use 1 byte for bools rather than 4
-dropped "official" windows build (suggestion to use WSL if possible)

This is Shed Skin version 0.9.2.

- started adding type annotations to shedskin (Shakeeb Alireeza)
- use CXXFLAGS instead of CCFLAGS in makefiles (Yuri Victorovich)
- add object address to default __repr__ (reported by Yuri Victorovich)
- FreeBSD compatibility fix (Yuri Victorovich)
- more scalable but slower type inference
- reimplemented {dict, set} using STL unordered_{map, set}
- added --float32/--float64/--int32/--int64/--int128 options
(--int128 not available under windows, awaiting C++ standardization)
- fixed memory leak for extension modules
- new pycsg example (constructive solid geometry)
- fixed c64, hq2x and pylot examples under windows
- ignore typing imports and any type annotations
- support for range.{start,stop,step,count,index,__contains__}
- generalized expr in [..]/(..) optimization to work in more cases
- support bytes.__contains__(int)
- support itertools.{pairwise, accumulate}
- support default value for dict.pop
- fix {str,bytes}.{find,rfind} negative start, stop arguments
- improved support for overloading __index__
- rewrote {str,bytes}.split to not use macros
- struct.{pack_into,unpack_from}: wrap negative index
- remove partial __del__ support, and just mention it is not supported
- (re)add io.StringIO (in part to test print function)
- added: print(flush), array.typecodes
- support 'n' and 'N' fmt chars in struct module
- removed --nogcwarns and always hide gc warnings
- (re)add tests for array, io
- cleaner print statement for common (no keyword) case
- many refactorings for readability
- fixed a large amount of g++ warnings

- optimized indexing (when not using --nobounds, --nowrap) (thanks to folkert van heusden)
- optimized list/tuple allocation (thanks to folkert van heusden)
- improvements from running ruff linter (thanks to shakeeb alireza)
- support python 3.12 (used deprecated 'imp' module)
- optimized struct.{pack, pack_into}
- fixed several bugs in struct.pack
- added special-case optimization: list-expression + [element]
- support syntax for sets: {a, b, ..}
- support for int.bit_count()
- support for zip(strict=True)
- replace usage of va_arg etc macros with variadic templates (faster and more flexible)
- removed boxing of arguments to print(), struct.pack().. cleaner and should be much faster.
- two new examples: a strong othello player, and a collatz sequence record finder
- fixed many common compiler warnings (-Wall -Wconversion.. and such)
- fix segfault on unhandled exception (ubuntu) by switching to -lgctba from -lgccpp
- various fixes for --long
- fix (translate) --silent
- fix itertools.{zip_longest, filterfalse} (renamed from izip_longest, ifilterfalse)
- various other minor fixes
- add some errors for unsupported features
- fix fysphun example to work again
- ported four examples to pygame

- Use CMake to generate output binaries (Shakeeb Alireza)

- Set {Exception, BaseException}.__class__
- Various minor other fixes and improvements
- ...
