Willian and I (and Daniel, indirectly) have discussed this some;  I 
opted for only implementing interators for faces and edges instead of 
also implementing sequences.  (I don't know of another way offhand to 
implement the len() operator).  I'm still trying to figure out the best 
way to handle sequence operators (assignments in particular) while still 
keeping things "thin" and not messing up how meshes are referred to 
elsewhere in Blender.
