[New-bugs-announce] [issue43443] Should shelve support dict union?

[Dominik Vilsmeier]

New submission from Dominik Vilsmeier <dominik.vilsmeier1123 at gmail.com>:

The docs of shelve mention that

> Shelf objects support all methods supported by dictionaries. This eases the transition from dictionary based scripts to those requiring persistent storage.

However the `|=` operator is not implemented, preventing a seamless transition from `dict` to `shelve`. So should this be implemented for `Shelf` as well? `|` on the other hand doesn't make much sense.

Otherwise the docs could be updated.
