This was first brought up by @hgmarques. The idea would be to expand the Bonsai.ML.Torch package to support creation of custom Sequential models within Bonsai. The nice thing about the Sequential model is that it acts as a container for a sequence of transformations, where the input to the forward method of a sequential model is passed serially from one input layer to the next layer exactly as the layers are ordered during the creation of the Sequential object. This seems like it would be a pretty straightforward feature to implement.
