I dont' see how this is consistent.  *arg and **arg correspond to the 
two different container protocols: sequence/iterable and mapping.  Which 
container protocol do you se ***arg as corresponding to?  Note that 
namespaces are just mappings, so if you want to treat a block like a 
namespace, **arg makes more sense...
