(Instead, I could have made the return value of add_memory be a tuple if psi4 is not None but just a single value if psi4 is None. Not sure if tuple-all-the-time is more or less confusing than return-value-depends-on-inputs, so I chose the former. If you want the latter, let me know).
Thanks Mark. I'm just gonna make another little change to the versions listed in the JSON file, and then as soon as the changes hit conda-forge, you should be good to go.
The return value of add_memory is now a tuple.
