We might want add a comment noting that the return type of F changes into a Deferred[T] if the original return type was not a Deferred.
I don't think we came to a consensus in #synapse-devs on whether it was okay to use slightly misleading type hints in this kind of situation.

Ahh, I didn't spot that this also happens in run_in_background. Hmm, maybe this needs more thought?

I think it should be tractable to add this to our mypy plugin to make it correctly convert the return value from awaitable to deferred?

This doesn't work if T is already an awaitable

@DMRobertson I think most of this PR was done in #11556. Should we close this for now? |

Agreed! |
Goal is to make
synapse.loggingpassno-untyped-defs. This is a first step.Some work also done in #10943 in this area.
