Associated type inference behavior was changed in apple/swift#32578:
derived conformances are now attempted before associated type inference.
This broke ParameterlessLayer, which relied on a TangentVector == EmptyTangentVector same-type constraint to set a
default TangentVector type witness for conforming types.
A workaround was added in several PRs (#1034, #1035, swift-models#620, fastai/fastai_dev) and is forward-and backward-compatible, but makes code more verbose. If possible, identify a way to support the old behavior.
