[Community] Heterogeneous Geometry Collections

[Aron Bierbaum]

I would completely agree that it is best to avoid heterogeneous
collections if at all possible Unfortunately we have to parse and
store a data feed. While we can currently do this using by parsing the
WKT and then storing in our database, writing tests requires the
ability to create the collections in Python. I will take a look at
adding support in 1.2.

Thanks,
Aron
