I'm working on updating libmamba to 2.0.X [1] but hitting the following

Error 1
I'm guessing 'SR.32262' is some kind of temporary variable. libmamba
has taken the (perhaps admirable?) step of compiling with -Werror so it
fails.
The pybind11/cast.h function is:
/// Collect all arguments, including keywords and unpacking (only
instantiated when needed)
template <return_value_policy policy,
typename... Args,
typename = enable_if_t<!args_are_all_positional<Args...>()>>
unpacking_collector<policy> collect_arguments(Args &&...args) {
// Following argument order rules for generalized unpacking
according to PEP 448
static_assert(constexpr_last<is_positional, Args...>()
< constexpr_first<is_keyword_or_ds, Args...>()
&& constexpr_last<is_s_unpacking, Args...>()
< constexpr_first<is_ds_unpacking, Args...>(),
"Invalid function call: positional args must precede
keywords and ** unpacking; "
"* unpacking must precede ** unpacking");
return unpacking_collector<policy>(std::forward<Args>(args)...);
}
and it error on the return line.
libmambapy/bindings/legacy.cpp:52:26: is
warnings.attr("warn")(total_message,
builtins.attr("DeprecationWarning"), py::arg("stacklevel") = 2);
This is all way above me - hopefully some C++ expert can chime in here.
