Passing unused parameters

I would like to keep a couple of parameters in my hybrid block in order to do some “manual” operations from time to time. If I don’t pass them to hybrid_forward I get an error (expected) but I pass them to the hybrid_forward and I don’t use them, then I get this error

UserWarning: Parameter MYBLOCKblock0_pippo, MYBLOCKblock0_num_dim is not used by any computation. Is this intended?
  output = net.forward(example_input)
Traceback (most recent call last):

If I user them with some stupid operation (e.g. summing them to my output multiplied by 0) everything works but does not look very clean/scalable.
