This is a _very_ old ticket, but it is still relevant. Possibly, this is only interesting for fermions, as gauge bosons are already specified as being massive or massive, and for scalars this is probably also not interesting. So depending on an external flags for particle lists, we should have to different types of spinors, massless and massive ones.
