AVOID. Use error_or_stopped(YourException{...}) if at all possible. Add a std::in_place_type_t<Ex> constructor if needed.

error_or_stopped
from_exception_ptr_slow(std::exception_ptr eptr);Provided for compatibility with existing code. It has several downsides for result-first code:
It is a debug-fatal invariant violation to pass in an exception_ptr that is empty or has OperationCancelled. See the dfatal_if_eptr_empty_or_stopped doc.
Not knowing the static exception type blocks optimizations that can otherwise help avoid RTTI on error paths.
An error_or_stopped holding eptr.
