Description
c2d of improper transfer function breaks silently since it goes through state-space, and isproper is broken, see https://github.com/JuliaControl/ControlSystems.jl/issues/85
Should we enable some way of discretizing a transferfunction other than going through state-space form?

Research direction
Start by reading the linked ControlSystems.jl issue 85 and then trace the c2d and isproper entry points mentioned here. Determine how improper transfer functions currently pass through state-space conversion and what alternative discretization behavior should be supported. Done means the failure is no longer silent and the chosen behavior is clearly validated.
