[windup-dev] Pileline.select() to get a table /// Re: Nested rules alternative?

[Ondrej Zizka]

Good news: I found it. The select(...) creates the tuples in a form of 
Row objects.
Problem is that our current API limits the output to Vertex as it frames 
it later.
We could add support for the Row object and create RowFramed which would 
hold the tuples of framed vertexes.
