Zygote uses the convention that tuples of nothing are collapsed to a single nothing. However, currently this convention is not applied to @adjoints. The PR fixes this, as suggested in FluxML/Zygote.jl#1464 (comment).

Thanks! Since most of the tests are on the Zygote side, I've opened FluxML/Zygote.jl#1466 with a copy of these changes to see what CI thinks. If everything looks good, will merge this.

Would be useful to add downstream tests with at least Zygote to this repo IMO.

Can this be merged? I encountered a similar error but not sure...

See FluxML/Zygote.jl#1466 (comment). We need to do some tests on the user-facing interface in Zygote, then this can be merged. I haven't decided whether it should be a breaking change or not.

Results in FluxML/Zygote.jl#1495 look good, time to merge and tag :)
