* Add err guard to capsule destructor

* only uses ostream currently

* can these be noexcept

* Add back header

* fix for older compilers

* This should at least be noexcept

* Add missing move

* Apparently not noexcept for old llvm

* Replace import numpy catch (...) with catch (error_already_set)

* Add missing const (not sure how those got lost).

* Add error_already_set_what what tests, asserting the status quo.

* Move PyErr_NormalizeException() up a few lines.

* @pytest.mark.skipif("env.PYPY") from PR #1895 is required even for this much simpler PR

* Move PyException_SetTraceback() with PyErr_NormalizeException() as suggested by @skylion007

* Insert a std::move() as suggested by @skylion007

* Use move converting ctor when making class staticmethod

* Add missing caster move in buffer func

* fix use after move

* add back move to staticmethod

* avoid shadowing with varname

* Don't return pointers to static objects with return_value_policy::take_ownership.

This fixes -Wfree-nonheap-object warnings produced by GCC.

* Use return value policy fix instead

* (perf): use an rvalue cast in func_wrapper

* Try to clarify comment

* Fix comment typo

Signed-off-by: Henry Schreiner <henryschreineriii@gmail.com>

* Add missing std::moves in enum_base methods

* Remove useless move

* Add one more std::move in print

* Further optimize print

* Some more misc optimizations

* ci: fix cuda issue

* ci: cuda 11.3-11.4 produce warnings -> errors

* tests: ignore unused warning for MSVC

* Update tests/CMakeLists.txt

* Fix py::cast from pytype rvalue to pytype

Previously, py::cast blindly assumed that the destination type was a C++
type rather than a python type when the source type was an rvalue.

* change iostream include to ostream include

* Add frozenset, and allow it cast to std::set

For the reverse direction, std::set still casts to set. This is in concordance with the behavior for sequence containers, where e.g. tuple casts to std::vector but std::vector casts to list.

Extracted from #3886.

* Rename set_base to any_set to match Python C API

since this will be part of pybind11 public API

* PR: static_cast, anyset

* Add tests for frozenset

and rename anyset methods

* Remove frozenset default ctor, add tests

Making frozenset non-default constructible means that we need to adjust pyobject_caster to not require that its value is default constructible, by initializing value to a nil handle.  This also allows writing C++ functions taking anyset, and is arguably a performance improvement, since there is no need to allocate an object that will just be replaced by load.

Add some more tests, including anyset::empty, anyset::size, set::add and set::clear.

* Add rationale to `pyobject_caster` default ctor

* Remove ineffectual protected: access control

* Test pickling a simple callable (does not work).

Currently only documents that it does not work. Starting point for future fix.

* Use re.search to accommodate variations of the TypeError message.

* PyPy: exercise full dumps/loads cycle.

* Adding explicit "broken" comment.

std::valarray.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

* get_name_or_throw->get_name_no_throw

If PyCapsule_GetName raises an error we should write as unraisable
to consume it and notify user, and then restore the error in flight if any.
This way this method called from destructor would not modify interpreter
error state.

* used error_scope struct

* Renamed get_name_no_throw->get_name_in_error_scope
