Is it possible to use a Flux.onehot vector together with other data as input to a Layer?

Can you be a little bit more specific about this? What do your data and model look like?

I have a time series that depends on some real valued variables and on the type of day (i.e. Sunday, Monday,…)  
I would like to encode the day information into a onehot vector and combine it with the rest of the variables as input.  
For know is use a for loop and convert the onehot vector for each time instance into a binary value and concatenate it with rest of the variables.  
It would be nice if `hcat` would work for such an application.
