Yeah, I'm just worried that it'll become useless without that. For instance, passing arguments to a function that uses *a,**kw is going to package your thunk into a collection, and that's how (eg) the logging module will process it. It's not going to be easy to have a simple AND useful definition of "this collapses the waveform, that keeps it in a quantum state", but sorting that out is fairly key to the proposal.
