Neither of these work, as in both cases default() wins over index() 
except when index is defined as 'sub index : Path', which isn't a good 
option for me.

And... I'd imagine that having both default and index defined with " : 
Chained('base') PathPart('') Args(0)" would lead to a collision and/or 
non-deterministic behavior...?
