Day by day it becomes more obvious to me that sooner or later 
segments/ways distinction will be back with us. Look at this.
A way (street) may belong  to many relations, right? Each relation
may contain different part of the street, right? Especially in big 
cities where bus routes can be relations and each bus may take 
different turns, there will bo no single way/highway comprising more 
than one segment (to be precise I think about lines between 
crossings which in case of curved street may comprise more 
segments). There will obviously MUST be invented 'street' replation 
which takes a few segmetns and gives them common name. The other 
relation (perish?) could contain all the objects that belong to a 
certain place including half of the segments of the streets that 
connects two adjacent places.

This shows a little problem which, however, should be automatable, a 
new object (node/way|segment) has to be assigned to a different 
object (relation) rather then assigning the  place relation to the 
new object.


I am just shatring my thoughts, maybe someone can come up with some 
thing wiser ;-)
