New submission from wim glenn <wim.gl...@gmail.com>:
https://docs.python.org/3/c-api/tuple.html#c.PyTuple_GetSlice
In the c-api it says (emphasis mine):
PyObject* PyTuple_GetSlice(PyObject *p, Py_ssize_t low, Py_ssize_t high)ΒΆ
Return value: New reference.
Take a slice of the tuple pointed to by p from low to high and return it
**as a new tuple**.
But when slicing the entire tuple, CPython will return already existing
instance, not a new tuple.
https://github.com/python/cpython/blob/3.8/Objects/tupleobject.c#L448-L451
I propose the language in the docs be loosened so as not to tie the hands of
implementation
