Hello Sean,
thanks a lot for your prompt response...and for all the work at
shapely: I'm pratically fond of it :)

No problem then, I'll wait for the trunk to stabilize. Btw the change
into numpy interoperability is very welcome: I find myself using zip a
lot of times to get back and forth the two representation.
