Description
It would be nice to have this implemented so one could use PyList::new, PyTuple::new & PySet::new with fallible iterators. One quick look into the source code showed me that the callback conversion code needs adjusting to make this possible (if possible at all).
Does someone have an idea if this is feasible or wanted at all before I jump in this rabbit hole to implement this?
Thanks in advance.

Research direction
Read src/impl_/callback.rs and trace the conversion paths used by PyList::new, PyTuple::new, and PySet::new. Done means determining whether fallible iterators can use Result<T, E> with E: Into and implementing the requested conversion if feasible.
