How to use it consuming input from a stream?

This is possibly related with #55

I want to parse a big CSV file line by line, and I hoped it was something like:

aCSVStream := 'myFile.csv' asFileReference readStream.
ZnBufferedReadStream 
	on: aCSVStream 
	do: [ :stream | (PP2CommaSeparatedParser parse: stream) row ]

But it didn't worked and isn't entirely clear to me what could be a way to parse input from a stream.
Is this possible right now?

Any suggestion to this? Maybe @kursjan ?
